If you're just looking to drill problems, I think adventofcode.com is more fun than Leetcode. What's worked best for me in learning new languages and such is trying to solve small problems I've had or just working on something I'm interested in. I get so burnt out just grinding generic programming problems. Lots of other great suggestions here.
