""23 things I didn't learn in college / grad school":

#12:
Be very protective of your time

.

Time is your most precious resource, and how you treat it says a lot about where you're headed.

Look back at your week (or month). Which hours do you wish you can take back? And why?

The most important question to ask yourself is: how intentionally are you spending your time?

We all need time to decompress, binge-watch something on Netflix mindlessly, or otherwise "waste" time. But let it be intentional.

At work, think twice before you commit to a meeting that has more than 3 people in it.

Any meeting that has more than half the people staring into their laptops for more than half the time is not worth anyone's time.

Another common way we all spend time poorly is "thrashing" on some task -- mindlessly trying things without making any progress. Watch for signs of this, especially when you're tired.

Sleep is a better investment of time than any activity done when you aren't fresh and mindful.

Protect your time so you can use it intentionally, mindfully.

Protect your time so you can be generous with it.
