What do you like to eat? Favorite cuisine? I'd suggest some focus to start. There are a lot of good suggestions in this thread about books and videos but I'd avoid picking random recipes to try. They won't overlap ingredients (or tools) and that drives costs up quickly. Instead, pick a focus (or two) of some kind. That could be a specific thing like ramen or pizza or a bit broader like breakfast or Mexican food.
Next I'd say you should learn how to do one thing at a time, learn to make tortillas but use taco seasoning and basic fillings. Next week buy the tortillas but make refried beens from scratch. The next week make salsa but buy the beans and the tortillas. Continue this until you can make every component and then pick a day and make everything from scratch. Doing this you will learn what you like making, what parts are worth your time and what you would rather just buy.
The method I propose here also scales well if you want to do some amount of weekly food prep to save time on weeknights - make a big batch of a component or two and mix and match your homemade items with store bought ones throughout the week.
Some pitfalls to avoid. Touched on this above but don't go to the store with a shopping list that is just the recipe - this gets expensive fast and is likely to result in lots of waste. Avoid specialty ingredients till you have practiced with cheap ones too. Also avoid special tools to start - you need a knife and a pan to get started. Not saying not to invest in good tools, just don't go buy a stand mixer or a mandolin until you've made enough things to know why a particular tool would be a good investment for you.
Last thing I'll say is that you'll burn things, add cinnamon instead of cumin, salt instead of sugar, your dough won't rise or you might drop all your hard work on the floor but it's part of learning - keep at it and try to just enjoy your time in the kitchen!
