The next time you are thirsty, hold up a glass of water in front of you before you drink from it, is it half-full or is it half-empty?
This is a decision that is entirely yours to make. It is also a decision that reflects your general outlook on life.
Your thoughts and how you react to external events are the only things in life you have direct control over. You cannot control certain situations, and you cannot control how other people behave, but you can control how you react to these events.
I once spoke to a high level manager who told a group of us, in no uncertain terms, that if you want to achieve anything in life and that glass is half-empty, have a nice day, but you’re not going to achieve much.
