I Quit Drinking: 7 Ways It Changed My Life and Business How to revolutionize your life and business by giving booze the boot-from an entrepreneur who has done it.

Let me be clear: I was never an alcoholic. I was a social drinker who enjoyed an after-work wine or two to unwind after a stressful day. On the weekends, I'd have some beers while watching sports with friends.

But this habit of a few "innocent" (but regular) drinks took a toll. They made me feel tired and sluggish. I was unmotivated and irritable. I woke up during the night. I wasn't performing well at work. (Excessive drinking costs the U.S. more than $200 billion per year, largely a result of lost work productivity.) I was growing a beer belly and becoming puffier in the face. I just felt average—maybe a five or six out of 10—in every area of my life.

After waking with a shocking hangover at the South by Southwest Festival in 2010, I decided to take a 30-day break from alcohol as an experiment. Thirty days came and went, and I stayed on the wagon. I haven't touched a drop of alcohol since.

Here are seven things I learned.

1. My persuasion improved.

Studies show that persuasion and influence have more to do with how rather than what you say. When people said, "Go on! Just have one," I pointed to my head with a sly grin and said, "Nah, I'm too strong in mind." Or I gave a polite answer like:

• "I'm driving."
• "I'm on a detox and taking a break from alcohol."
• "I'm not drinking tonight. I have to get up early in the morning."
• "I'm good with water for now. Thanks."

I never apologized for passing on the alcohol. I owned it and felt totally comfortable without drinking. When people saw my confidence and playfulness, no one thought that I was weird for not drinking; rather, they were impressed by my discipline. That discipline carried over to new business ventures.

2. I made new friends and contacts.

A barrier to quitting drinking is the perceived social pressure to drink. In the book "Evolutionary Psychology," professor David Buss talks about the real dangers that our ancestors faced when ostracized from their tribe: no shelter, safety, or food. These dangers don't really apply in the modern world. Although I didn't fire my friends, I found a new tribe of people at fitness classes, entrepreneurial masterminds and meetup groups who drank moderately or not at all. I began hosting monthly alcohol-free poker nights at my apartment for local entrepreneurs, which helped my businesses by growing my network. (When you host something, people are more inclined to help you.)

3. My social skills improved.

With a clearer mind, I thought more about how I could help people, rather than how they could help me. I learned to engage people in conversation by asking questions like, "Tell me about yourself," or "What's your story?" or "That's interesting, tell me more." I wasn't relying on alcohol to loosen up; I was just relying on people skills, intense listening, self-assurance and confidence.

4. Good habits replaced the bad.

New patterns can override old neurological patterns and habits, says Charles Duhigg in "The Power of Habit." By focusing on one "keystone habit" (not drinking), I taught myself how to reprogram other routines in my life.

I ate, worked, slept, and saved money differently. I started waking up earlier to go to the gym or for a hike before work. Instead of having a sit-down meeting, I'd go for a run with someone instead. Making plans for early the next morning gave me a great excuse to go home early, get to sleep, and wake up early to attack a beautiful new day. This all resulted in better productivity throughout the day.

5. I handled stress better.

Alcohol cravings are usually a response to stress, boredom or loneliness. When I felt that "need" to drink, I held my breath for 10 seconds and exhaled for 10 seconds. Or I took a brisk walk around the block and felt better in five minutes. Or I did 60 seconds of star jumps or burpees.

Moving your body from a stressed emotional state to a huffing and puffing state relegates alcohol to the last thing on your mind. You can apply the same method to crush any craving when you need to get stuff done.

6. I celebrated differently.

Before quitting drinking, I'd always celebrate success—like a job promotion or product launch—with drinks. These days, I'll go out for dinner or take a road trip to declutter my mind and strategize. When entering a bar or restaurant, I'll confidently walk up to the bartender and say, "I'll take an ice water with a piece of lime, please."

7. I lost weight.

I lost an incredible 13 pounds of fat around my stomach after 30 alcohol-free days. These factors explain this:

• Alcohol slows your metabolism. The body breaks down alcohol before fats and sugars.
• Alcohol contains a lot of empty calories. A pint of beer has about as many calories as a slice of pizza.
• Excessive drinking makes you eat a lot more junk food like fries and desserts. (Staff at the New Scientist saw improved blood glucose balance after a month without alcohol.)
• Quitting drinking gives you the energy to be more active.

I'm not saying that you have to quit drinking forever. But what opportunities are you sabotaging with a few "innocent" drinks?

Building a business involves sacrifice. For some entrepreneurs, healthy habits are the first to be neglected. Meetings, emails, calls and extinguishing fires take priority.

Not drinking transformed me—personally and professionally. And it will transform you, too. Try it. I bet you I'm right. And if I am, you owe me a glass of water with ice and a piece of lime.
