The reason you're not feeling motivated is because you don't have a clear goal. You do have a goal, but it's only that you want to make a lot of money. With just that, you'll only experience FOMO (fear of missing out), not money. Hard work is your responsibility, but you need to set small and immediate goals. For example, if you're studying DSA, it's not something you can complete in one day. A goal for now should be to master one topic thoroughly until you can solve all medium-level questions, and slowly, you'll crack it. This is crucial at every stage of life. Motivation will come when you start achieving small things, and eventually, everything will fall into place one day. ♥️
