Try cooking. The skill cap is high, it doesn't take much to make things OK, and you gotta eat. it has helped me a lot. Plenty of times I don't want to do it, but it's hard to put off for long. You can screw up a lot, and the results are still edible. Every damn meal I make has problems. Usually it's pretty good, but there are things I can do better with the output and the process. No matter the outcome, I feel better…
Cooking is one thing I'm terrible at: there is no feedback loop at all. No matter how much time I spend on 'experimenting', I don't get any better. Many people simple cannot fathom this. They deny the existing of any such possibility.
Smell the spices before you try them out, use small amounts then taste the food while it's cooking. This works for almost anything that isn't baked. Google to find out what spices intensify through cooking (Fenugreek, Cayenne Pepper, etc.)
Also check out The Food Lab's book for information on what different things do, so you can construct a mental model of it.
