Life is a Choice
What do we really HAVE to do to make it? Breath. Eat. Sleep. Stay at a relatively constant temperature. Maintain homeostasis.
Everything else in your life is a reflection of choices that you make. Going to what you choose to think is a crappy job? Dealing with family drama? It's all your choice.
I know. Some things seem so incredibly critical to survival/well-being/sanity/stability that we can't see them as decisions we're making.
But really, truly, in the end -- you are choosing your path, every single day.
