Have you ever wondered why the president of United States of America, Barrack Obama, chooses to wear only two kinds of suits i.e. blue and black?
Because he wants to save his mental energy for far more important decisions than to worry about his daily dress code. That’s a conscious strategy to bring focus on the most important things in life.
The daily quota of willpower, which is depleted by every decision you make daily, is limited for every body. Don’t waste it on insignificant decisions.
When you decide to eliminate every single non essential stuff from your routine, then and only then can you devote your time and and energy to something meaningful.
And if it means sticking to just one grey t-shirt, like Mark Zuckerberg, so be it!
