No guru, no teacher, no master, no angel, no muse, no aliens from Mars, will ever do it for you.
Only you will.
You have to be scared out of your mind, you have to be feeling you are risking everything.
But you also feel that there is a (small) chance it will be OK.
And deep down inside you have this soft voice whispering:
"If not you, then who? If not now, then when?" [Paraphrasing John E. Lewis]
