It is hard to erase problems. I am not really sure what to say about in terms of a solution. My own approach is to do Physics and learn Rav Shach and other parts of Torah and hope that the light of Torah will erase all my problems. That is the best I can figure out. I also try to say over to myself a few statements of Musar in the morning when I get up that deal with issues I need to work on. There is a great Musar book called "Madragat HaAdam" by a disciple of Reb Israel Salanter that has a passage in it about Trust in God that he brings from the Gra's commentary on Proverbs which I try to say over to myself to remind myself about trust in God.
But that is just for me.
I am not sure about the issues that other people need to work on. But whatever they are I think the best idea is: learn Muar and when you find something that deals with some problem you are having then to write in down and repeat it to yourself every day when you get up in the morning
