What you are going through is an EXTREMELY common thing... Almost everyone goes through it at the beginning... I am not, by any means an "expert" programmer, but I can tell you that you there are only two good reasons to write your own code instead of using accepted modules: 1. You can do a better job 2. You want to learn how it is done. The problem with writing your own modules to replace existing ones is that you could be spending that time studying more advanced topics(or other modules). It is perfectly fine with me if you never progress any further, personally I don't need the competition. :)
