One subject I am asked about on Sosai's philosophy is about not quitting.
Those that are succeeding and are thrilled and joyful in the unfolding will often tell you, "I've dreamed this since I was little. I imagined it, I pretended it, I used to practice with the hairbrush pretending it was a microphone." Purity is the alignment of energy. Doesn't matter what anybody else thinks about anything. It only matters what you think about it. ^^
Just need to train your mind to focus, focus, focus!
