Some times in the day time when you dont want to sleep, you might feel sleepy. But even if you are sleepy, if you like a task very much, you dont feel sleepy anymore.

Same thing applicable to stress. When I am in stress, I dont want to do any thing. But I would be interested in doing things that I like very much.

So I created a tag called "booster". Where I collect interesting things with no due date. These are all the interesting tasks which I like to do, but cant allocate time for it currently.

Whenever I feel sleepy or in stress, Instead of wasting the time, I ll check that list and do the tasks. In addition to utilizing time effectively, it makes you fresh.
