It's important to find balance. I've found when I am penny pinching and crunching every last cent that I am miserable. It's important to be disciplined but not over anxious.
Love the "buy six good books a year" suggestion @billionairesmind
I learned a long time ago - the only difference between you this year and last year are the books you've read and the friends you made.
Reading good books that helps you learn a new skill is critical if you want to succeed in the future. People will rather spend time reading Facebook posts and commenting rather than read stuff that will help them plan for a better financial future.
