You can only work on one problem/situation at a time.

So many people believe this to be the case, so much so that they usually will think they have so much to do that they just don't do anything or they work on a surface problem because they are afraid to look deeper.

The problem with this is, if you manage to clear the problem you will not get the result you are after, you will not be 'cured' or 'fixed'

The reason for that is you are not really hitting what is holding you back.

Look beyond the surface and tackle the main issues that are causing the smaller ones, don't hide out of fear, work on it out of desire to be better.
