Man that's tough question.
Growing up, my mom did most of the cooking, and it was not good. She'll even admit to that. Everything was bland and overcooked.
My dad did the grilling, and it was horrible. He could turn steak into shoe leather better than anyone.
When I was 26, and bought my first house, and I bought a grill. Then I bought some cookware. I made a farking mess out of a lot of groceries at first, but, I learned, and I searched for cooking wisdom, and year after year, I got better.
My first quest was for a really good steak. I burned a few before I figured it out. Then, I worked on chicken and fish. And I just kept working.
I got my first breakthrough when my wife gave me a Weber Master's Touch for my birthday in 1995 -- a red one. I finally had a good grill. It made a big difference.
From there, it has really just been a trial and error progression. I'm still learning, and hope to keep learning forever. It's a blast! I love to spend a Sunday cooking, and then eating the results.
Funny thing, both of my parents have actually learned to cook and grill better from me. When I go home to visit the parents, my dad watches me work his grill, and cook up good food on it. The son teaching the father -- and we have a good time in the process.
