What is the biggest lesson you have learned in your career? Chances are you can name it off the top of your head. We learn lessons every day, we just don’t always take the time to stop and think about them. It’s important to ask yourself what you’ve learned at the end of each day. 

What meetings went well and why? What interactions would you have changed? What would you have said yes to and which commitments should you have passed over? Did you find yourself doing something that was really someone else’s work and you did it because you could do it faster and better? Take time at the end of the day to take stock of what you have learned - it only takes a few minutes and it can be an incredible boost to productivity.

Too often we allow co-workers to fall into the habit of coming to a meeting late. Even if the meeting starts on time, we often stop to give them cliff notes of what they missed. This takes away from the group’s productivity and when you think about it, such behavior ends up costing money because staff who are being paid are in an unproductive mode. 
When you let everyone know that a meeting will start promptly at a given time and a summary will not be provided to late comers, then follow through with this plan, participants will begin to arrive on time.
