I can relate to being a picky eater and not liking the taste of things. I go through hundreds of cookbooks and it's difficult to find recipes I like. Forgetting an ingredient is normal. I'll often forget baking soda at the end of the recipe and the result will be flat. You may want to double check the recipe after you've done anything to make sure everything's there. I've also been having trouble lately making sure all the ingredients I took out are put away in the refrigerator and often find something that went bad when it was accidentally left out. What I like about cooking is that most flops are still edible and at their worst, if you don't like it, someone else might.
You mentioned you like fruits and vegetables. You may want to go to the local farmer's market or vegetable stand and see if there are some more unusual fruits and vegetables to try. I've been experimenting with making squash as a side dish. If you can get the squash open, it's fairly easy to make. Asparagus is another quick option. I've been using a microwave steamer. It's great for reheating vegetables or certain leftovers. If you want to avoid the plastic varieties, I just found a silicone based one by Cuisinart. Also, if you're making pancakes, waffles might be another option to try. Crepes are another possibility and you can also use them as egg roll wrappers or in lasagna or manicotti dishes to replace store bought versions. Pasta is fairly easy to cook. I've been boiling lentil or lentil/rice pastas a lot lately. A nori roll with rice and/or vegetable filling is another easy option. I've also been experimenting with collard greens as a wrapper lately. Another nice cooking tool I've found is a rotary slicer. It's useful for grating foods or making baked french fries. I have a Vitamix, but I'll frequently just use an inexpensive coffee/nut grinder to grind flax, seeds or grains. The Vitamix is good for making ices from frozen fruits and making seed/nut or fruit butters though. I've even used it in place of a stand mixer when I make a crepe batter.
If you want to enrich what you're making, there are ways to sneak healthy things into a recipe without altering the taste. Most recipes that include sugar have too much and you can lower it gradually without missing it. There are tricks like the Cornell triple rich formula. Substitute part of the flour in the recipe for healthier ingredients like that formula or just add a spoon of healthy ingredients like flax, etc. Add more vegetables to dishes. If you're having a pizza, add a lot of vegetable toppings. I like to use unbuffered vitamin C powder as an acid that works with baking soda. Heat might destroy a lot of the C, but you're still getting some that you might not otherwise get. It depends on your goals but you can usually alter recipes you like in small ways to make them more nutritious.
I really like Nicolette Dumke's books. She uses very basic ingredients and explains how you can substitute ingredients for ones that you're more comfortable with. You can find some of her recipe books on archive.org or possibly at your local library.
I use HTML for my formatting and wkhtmltopdf to create documents instead of latex. Some people prefer markup for document formatting. Plain text has a lot of benefits and is very portable. It's useful for notes, todo lists and there's no reason one can't store recipes that way.
I read tons of recipes books and I feel lucky if I find even one I like. However, I do find something useful that actually tastes good once in a while. So, I feel like it's worth the effort to keep searching for new ideas. Good luck in your own search. If you come across any useful recipes along the way, I hope you'll share them.
You may be able to freeze them and use them later although I think egg whites freeze better than yolks. I have some cookie recipes that use just the yolks. I'll often save up the whites from a cookie recipe in the ice cube tray in the freezer and when I get enough, make angel food cake with it. Was surprised, but frozen egg whites fluff/rise very well in angel food recipes. Cold egg whites can easily be whipped and they don't need to be at room temperature. They just need to be defrosted You can also use yolks in omelette or crepe recipes.
