Improve your complexity analysis first, and learn other algorithms such as binary search and prefix sums. Dynamic Programming is an intermediate/advanced topic that requires familiarity with time complexity and common data structures. If you're looking for a general roadmap, consider the USACO guide: https://usaco.guide/. As you can see, even basic DP is in gold, so you should save that until after you've learnt more algorithms and solved more problems.

Recursion helps a lot to understand the DP concept.
