Managing Your Schedule Like a Boss: Tips the Experts Never Tell You Time management is at the top of the short list of reasons why some people succeed and most don't.

Lou Gerstner, the former CEO of IBM, once said, "Never let anyone own your schedule."

I don't know about you, but I love that quote. It's so simple, yet true. After all being deliberate with your time is one of the best ways to have a happy life in the business world. Of course, try as hard as you can, that's not always the reality. Life is kind of known for throwing a monkey wrench into your plans every now and then.

But, it's still possible to manage your schedule like a boss by following these can't-beat tips.

Create a routine.

Next up you need to create, and stick, to a routine.

Start by blocking times for specific activities, such as checking emails, exercise and spending time with your family. You can then convert your calendar into a series of blocks for you to place activities in the prepared spaces. If something isn't planned and placed into a block, don't do it.

Keep in mind that your routine will probably change throughout the year. But, it's better to have a plan that changes than no plan at all. For example, if you're launching a startup, then you should block times for activities like customer discovery, coding and hiring. Next year you may have to block out times for marketing, growing your business and customer service.

Carry a schedule and record all your thoughts, conversations and activities for a week.

"This will help you understand how much you can get done during the course of a day and where your precious moments are going," write Joe Mathews, Don Debolt and Deb Percival on Entrepreneur.

"You'll see how much time is actually spent producing results and how much time is wasted on unproductive thoughts, conversations and actions."

Add time buffers to manage your schedule.

Have you missed a couple of deadlines because you jumped from project to project? It's probably because your didn't add time buffers. A buffer is something like this:

You just landed a new client for your freelance business. They assign you a deadline to complete the task. Instead of entering their exact deadline, your put your own deadline that's 24-48 earlier. Those hours are the buffer.

Why's that such a big deal? When you have a buffer, and something happens that you can't control, you still have those 24-48 hours to meet the deadline.

Schedule your calendar like a to-do-list.

If you have things on your schedule that have to be done, I personally like scheduling out time on my calendar for them. Much like a meeting, they have a set and scheduled time for this task to be accomplished.

For some people like myself, this includes blocking out time for working out, eating, walks and other important activities in my life. If I don't make time for them, other things will always get in the way. I find that when I block out those times on my schedule, I'm much more proactive as well as I feel better about myself.

Use batching and time-blocking.

In my early days of freelancing I multitasked like it was going out of style. I eventually realized that doing more than one thing at a time is ineffective and stressful. I was stressed beyond endurance because, as research now shows, the human brain isn't capable of multitasking.

A study conducted by Microsoft Research, shows that switching from task to task is less productive than staying on the same task, or the same types of tasks, over a block of time. That's why batching is so awesome.

Batching is basically where you find similar tasks and then lump them all together to make a task-batch. You then sit down, set a timer, and focus only on those similar tasks. For example, setting aside 6 am to 7 am to check emails and then 8 am to 10 am to write blog posts.

Another strategy that you should try is using time-blocks. When you have outside meetings, block two and a half days per week for those meetings. Only attend those outside meetings during those time-blocks. To make blocking more effective, color-code your calendar so that you can visually glance at your calendar.

Chandler Bolt wrote a great book, The Productive Person, that you should read if you want to learn more about time-blocking.

Optimize time for different meeting types.

To be honest, 30-minute meetings and 10-minute calls are ideal. A 10-minute phone call with a prospective client is more than enough for me to know what their needs are and if we click. Better yet, Google Hangout or Skype can be used to see the person instead of just hearing them.

If you have a remote team, you can host a virtual meeting via Zoom,RingCentral Business, Zoho Meeting, Join.me or GoToMeeting. Here are some suggestions on the types of meetings that you might want to book and schedule:

• 45-minute meeting that's outside of the office. Allow 15 minutes for travel and 30 minutes for the meeting over coffee.

• 30-minute weekly staff meeting.

• 30-minute meeting in the office to get to know colleagues or catch up.

• 15-minute daily standup if you're a startup or leading an engineering team.

• 10-minute phone call to offer someone advice.

Whatever meetings you decide to hold a meeting, you should group them into blocks. If you think that a particular meeting needs more or less time, then you can adjust the block accordingly.

Still, just remember that it's impossible to get everything done. "Also remember that odds are good that 20 percent of your thoughts, conversations and activities produce 80 percent of your results," say Mathews, Debolt, and Percival
