I think he said it pretty well. It's a lot of trying things out to find out what works.
Follow all the little details of recipes, even if they sound stupid. "Add slowly" means seriously, add slowly. A lot of cooking is just doing things with the right amount of heat and doing things in the right order. But in time, you'll do it without even thinking about it.
For breakfast today, fresh rolls from the bakery, and two burgers. I put in very finely diced onion and just a splash of worchester. I hadn't done it in forever, but typing about it made me want it. Oooo, they were good. It's rare to get anything that good in a restaurant.
Only use knives on a surface that they can cut into. Even touching the side of the edge of a blade with your finger will dull it. Use wood cutting boards, and clean the board when you're done. One great cutting board will last you many years. I'm only on my second one and I've cooked for a household of 3 of 10 years. If you wanna be quick and lazy, paper plates work too.
When you get better, you can try fun stuff like stir fry.
Look into crock pot recipes. Chop up some potatoes and carrots, wash off a beef roast, and put all 3 into a crock pot for a few hours. Yum.
