The difference between successful people and really successful people is that really successful people say no to almost everything - Nassim Nicholas Taleb

It is not possible to have fun when you try.

"As a matter of fact, your happiness depends far more on the number of instances of positive feelings, what psychologists call "positive effect", then on their intensity when they hit. In other words, good news is good news first. How good matters rather little. So to have a pleasant life you should spread those small effects across time as evenly as possible. Plenty of mildly good news is preferable to one single lump of great news. The same is property in reverse applies to our unhappiness. It is better to lump all your pain into a brief period, rather than have it spread out over a long time."

Greatness starts with the replacement of hatred with polite disdain.
