It's not the tools that you have faith in - tools are just tools. They work, or they don't work. It's people you have faith in or not. Yeah, sure, I'm still optimistic I mean, I get pessimistic sometimes but not for long.
For you to sleep well at night, the aesthetic, the quality, has to be carried all the way through.
Your time is limited, so don't waste it living someone else's life. Don't be trapped by dogma - which is living with the results of other people's thinking. Don't let the noise of others' opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition.
Stay hungry, stay foolish.
