Try to create products or services instead of trying to solving coding challenges. They are fine until one point. Puzzles can keep getting harder which might be increasing your frustration. On other hand, when you solve real life problems (they might not need complex algorithms but you've to figure out a lot) the result is huge reward which is not in case of coding challenge. There's another puzzle harder than the one you solved. Also the impact of product or service or the optimization that you did might save lot of time and money of others while paying your bills at the same time.
