Tips for making cookies? 🍪

So every time I try to make cookies I fail. Cakes I can do with no problem but cookies nope. I've tried following so many different recipes to try and find one that works but still nothing.

I want thicker gooier chewy cookies. But they always end up really thin and crispy?

I tried a batch today but have only cooked half, which came out badly. So is there anything I could do to save the second half and maybe make successful cookies tomorrow?
