It's okay if you don't find these problems to be fun. Some people like crossword puzzles, some don't. If you can't solve a problem, it doesn't say anything about you, except that you haven't yet practiced using that particular algorithm/technique enough. It most definitely does not say that you are stupid, although some ppl would have you believe that. I'd recommend that you only solve problems that are extremely easy, on websites like https://www.spoj.com https://www.spoj.com or https://www.topcoder.com https://www.topcoder.com or old google code jam questions. Pick a single website (I recommend codejam) and do only the easy ones for a few months. It's hard to argue against the happiness that comes when your program passes the tests. The point is not to sharpen your skill but to get used to the feeling that your program passes ALL the tests cases. If you get to a stage where you're completely sick and bored of easy problems, pick a slightly more difficult problem with basic algorithms like plain BFS or DFS. Try it for just a day or two and when you can't solve it, read the published solution. Try to understand it, apply it manually to the test cases and once you're sure that you've completely grasped the solution, implement it and see if it passes all the tests cases. Take it slowly, and return to easy problems often. This could take you pretty far in terms of enjoying the process. :) At least that's how it worked with me -- I liked the high of getting a program "accepted".
