Both in my personal life and in trying to spread the desire for liberty beyond my own brain.
With liberty, if you allow The State to dictate your definition of "success", pessimism seems inevitable. Even if you were 90% to your goal, the enemies of liberty wouldn't acknowledge it, and if you listen to them you'd think you are no closer than when you first began.
You don't have to change the whole world- you only have to change yourself- and the way you deal with the world. Your life will improve at that moment and any change beyond yourself will just be icing on the cake. What are you waiting for?
Oh, and "4/19!"
