You are looking at the situation from the wrong angle. Frameworks and languages are tools you use towards solving a problem. In the same way that mechanics don't spend their days wondering how they will use their wrench but rather what tools they need to fix an engine, you need to focus on a problem that needs fixing. Find a problem in some subjects you like and fix it.

Also, make a plan so you see an end. Doing something without figuring out when you will quit is a sure way toward quitting before you get anything accomplished.
