Making decisions is possibly the hardest thing I ever do.
The less decisions I have to make, the happier I find myself.
Of course, this does not apply to areas of life where decision making is either a team effort (like relationships), or part of my responsibilities (like career tasks).
We have all committed to doing things we were not entirely enthusiastic about, or over-committing to a vast amount of things that are mediocre. Life is too short to be consumed by the mediocre.
Say yes to less, say yes to better; this is the way to go.
