5 Big Questions That Entrepreneurs Should Ask Themselves Also, advice on how to define yourself from Malcolm Gladwell.

This article is excerpted from Entrepreneur magazine editor in chief Jason Feifer's monthly newsletter, The Feifer Five. Each month, he sends out five insights to help you think more entrepreneurially. Subscribe here.

And just as I ponder the meaning of this newsletter, I have some sizable insights for you to ponder as well -- about how we as entrepreneurs define ourselves, how we can think big while still zeroing in on the little stuff, and more. The table of contents:

1. How do you define yourself? (Malcolm Gladwell has an answer.)

2. Are you sweating the small stuff? (Just Salad is!)

3. What do you do with rejection? (I hung it on my wall.)

4. How do you react to others' success? (This reader did it... poorly.)

5. Are you easy to reach? (You should be.)

Let's get some answers. Here we go!

1. How do you define yourself? (Malcolm Gladwell has an answer.)

When you hear the name Malcolm Gladwell, you think of something: a particular kind of writer, or podcaster, or whatever. But Malcolm Gladwell doesn't. I spoke to him recently, and was inspired by the way he thinks of himself. He aggressively does not define himself. "I think it gets really dangerous -- if you're someone who's doing something creative -- to start to define what you do," he tells me. "Even if it's a correct definition, it's limiting to have that thing in your head. It starts to constrain you."

Then he expands on that idea a little more:

"I'm open to suggestion. The most important thing is never to make a decision about yourself that limits your options. Self-conceptions are powerfully limiting. In the act of defining yourself, you start to close off opportunities for change, and that strikes me as being a very foolish thing to do if you're not 85 years old."

Self-conceptions are powerfully limiting. I'll be repeating that the rest of my career.

2. Are you sweating the small stuff? (Just Salad is!)

I noticed an interesting change recently at Just Salad, a chain that I often buy lunch from. I asked the CEO to explain it, and his answer is a nice insight into the relentless tinkering that's requires to run a strong company.

Some quick background: Just Salad offers reusable bowls, which are both eco-friendly and encourage customers to come back more often. (If you opt for a reusable bowl, instead of a disposable one, you get some free salad toppings.) Here's my bowl, which I got maybe a year ago.

If you squint and look really close, you'll see Just Salad's logo. It's imprinted onto the bowl, almost imperceptibly. But recently, I noticed a design change:

A big, visible Just Salad logo is on each bowl now! I emailed Nick Kenner, the founder and CEO, to ask what's behind the change. I figured it was more complex than just a little bowl design upgrade. And I was right. Here's what he wrote back:

"The new reusable bowls that you described hit the stores about a month ago. About six months ago we did a strategic review on how we can make the reusable bowl more prominent in our locations. This involved:

• Better location of where bowls are kept

• More prominent signage in-store

• Better signage on bowl, as you indicated

• Recognition from media and nonprofits on our reusable program

• The EPA actually recognized us in June at a ceremony at their offices as the largest restaurant reusable program in the world!

"All this, as well as general political environment (as the White House turns back on protecting the Earth, others seem to want to try harder to protect it right now), has led to peak bowl sales."

How great is that? The companies that grow and thrive are the ones that constantly reexamine the details. Make it a prompt for yourself: What little thing have you left alone for too long?

3. What do you do with rejection? (I hung it on my wall.)

Want to see one of my favorite rejections? It's this:

Recently, people on Twitter were sharing rejections they'd gotten, and it made me think of this old one. It came from an editor at an old job, who wrote these words on a story of mine. He clearly wanted me to feel embarrassed, but know what I did instead?

I hung it on my wall like a trophy. As if to say, I don't take this guy's crap seriously. I'm better than he thinks I am.

Rejections are only as powerful as you let them be. We've all been rejected. When you are, don't bury it. Hold it high. Let it fuel you. Let's keep going.

4. How do you react to others' success? (This reader did it … poorly.)

We put a sharp, ambitious 13-year-old on the cover of September's Entrepreneur magazine, and have received an overwhelming number of positive messages about it. But I also got one angry email. I want you to read it, and witness the ugliness of resentment.

Here's what a man named Mel emailed me: "It's so heartening to realize that if a ditzy-looking kid can become a millionaire so easily, I must have completely screwed up my life, and despite all of my hard work and efforts, I'll never be an outlier like that. I've tossed the magazine, canceled my subscription, and am now facing reality. Thanks so much."

Good, Mel. Cancel the subscription. Go do something else with your life, because clearly entrepreneurship is not for you. Entrepreneurship is competitive, of course: We compete against ourselves, our peers and the industry at large. We're out to prove our doubters wrong. We want to win. But we never win by playing the victim.

I get it -- this isn't always easy. Someone will always be doing better than us. But we cannot not allow ourselves to be consumed by resentment. We cannot sit around saying, "It shoulda been me, not her" -- because that, Mel, just means we're sitting around not helping ourselves. Focus on you, Mel. Celebrate the successes around you, or at least learn from them. Resentfulness will get you nowhere … and nowhere is where I suspect Mel is.

5. Are you easy to reach? (You should be.)

Earlier this month, I was trying to contact a writer I might want to work with and couldn't find their address. It's not in their social media. It's not on their website. It's nowhere. And this happens more often than it should -- not just with writers, but with entrepreneurs, with executives, with lots of people of interest. What are you protecting against? The arrival of a few unwanted emails, at the expense of potential work and partners? Take it from me, a guy whose email address is easy to find and who receives a lot of email: It's not hard to hit delete on the junk. And it's awesome to receive the good stuff.

Just recently, I assigned a story to a writer who wasn't my first choice. Know who was? Someone I spent five minutes trying to find an email address for, and then gave up. Maybe they didn't want the work! The person I finally did reach was sure happy for the work. (And they did a great job … so it worked out for all.)

Seriously: Go google yourself right now. Does a site with your email address show up high in the rankings? No? Fix that!
