No pain. No gain. Heck, one of my random passions over the years was cooking, and I definitely had my share of suffering and bouts with doubt when things did not go right. In fact, I had a lot of duds in many cooking experiments. I literally tasted my various failures, yet they were equally good learning experiences. So I kept at it. I never gave up.
I am glad I was persistent, and now my passion for the craft grows constantly.
