The quality of your life is directly related to how much uncertainty you can comfortably handle.
Pain is part of life. Suffering is an option.
Knowledge is NOT power. Knowledge is only POTENTIAL power. Action is power.
You can't wait for the perfect situation. Find something you love. People you love. And get out there and you'll discover it.
Execution will trump knowledge every day of the week.
There is no such thing as failure. There are only results.
