I had this problem, too. This stuff helped:

-Asking my good cook friends what they kept around as "staples." This, in my mind, is a collection of stuff that can be combined in any way without producing bad flavor.

-Giving myself way, way more than enough time from start (inspiration or recipe-following) to finish (cleanup).

-Consciously forgiving myself for not being instantly good at something. Also -- and more importantly -- I forgave myself for not caring that much about variety.
