One thing to keep in mind is that you have limited mental resources and can really only do a couple things effectively at a time. Thus you are hardly a bad person for concentrating on a couple of areas at once and ignoring other areas as they are for the time being.

To figure out what you want to concentrate on, you might sit down with someone make a list of all the different things you could try, and figure out which 1-3 seem the most promising and then make a plan to try those. Then, after an appropriate length of time you revisit the issue and find a couple more things to work on.
