Back in 2009 our youngest was born and I had lost my job due to the economic downturn. My wife was the cook at the time, but was also the sole bread winner as well.
I had some basic skills in the kitchen, but really could not say I could cook. My wife was a great cook. However, it did not make any sense for her to work a 12 hour day and come home to cook. When I had been home with the baby and our older son all day.
So I had her teach me what she knew. Mainly it involved in how to read recipes. Learning the difference between a TSP and Tbsp and those types of things. While I would not say I have a talent for cooking, I did have a penchant for it. That lead me to cooking almost every day and discovering that a lot of getting good at cooking is practicing cooking techniques.
Fast forward to today and I've been a hobbyist cook for 17 years. I can confidently open any cookbook to any page and at least competently make that recipe, if not put restaurant quality meal on the table.
Am I as good as professional cook or chef? Oh hell no. I'm a home cook... A great home cook, but still a home cook. I'd probably be lost in a professional kitchen.
