OK. Here is Tip #1.
Alphabetize your spices! I know it sounds silly and like it might be a lot of work, but it is one of the best things I’ve done in the kitchen. There is nothing worse than needing a spice, knowing you have it, but being unable to put your hands on it. The best thing to use for spices is a lazy Susan. If you don’t have one, buy one. And get a double-decker one if you can. And don’t buy huge (Costco size) jars of spices. Buy the smallest container you can. Even if it’s more expensive, odds are you won’t use up the spice before its shelf life is over.
