Totally agree. It's so easy to overthink cooking. Take off the exec-chef-in-restaurant apron and focus on the simple stuff:
- Add salt/pepper/spices by hand if you can. Shakers/larger-volume canisters lead to over-application, but it's so easy to grab a little bit of salt, apply, taste, and do it over again until you hit the right mark
- Learn how to cook in a single pot - stews/soups/etc. Saves on cleaning, and broths packed full of nutrients
- Use a crock-pot/slow-cooker. Dead simple, very low risk, produces significant quantities of food
- Learn about portion sizing. So much of over or under cooking is applying the same technique and timing to two different quantities of food. 16 oz of steak cooks differently than 8, same for veggies. Buying the right portions consistently solves so many problems
- Given the point above, learn about an oven -- convection vs. radiant heat. Convection cooking is fast, easy, and awesome.
- Learn how to store stuff properly. You'll spend a fortune if you regularly trap your veggies in air-tight containers. Many of them don't need and are worse-off in those containers. Learn what stuff should be near or away from other vegetables. Good example: if you put your avocados and tomatoes next to your cucumbers, kiss the latter good-bye -- they'll go bad way faster due to the gas emitted by the two others
- Finally, it goes without saying -- not everyone likes what you do, so it's ok if your most exquisite dish doesn't go over perfectly with everyone.
