I love this quote and I agree with it. I would describe myself as being very independent. I think it's really important to be able to do things on your own and not depend on anyone else. The only person you can ever fully depend on is yourself.
Letting your happiness depend on something unstable, something maybe wonderful, but something you can't keep, is reckless, and recklessness is usually unwise. It's fun, that's for certain, but it doesn't end well. I need to learn what will never change about me and what I think and depend on that for happiness.
