Here's a challenge to all you brush- and resource hoarders out there:

go into your drawing program of choice, create a brush folder/group/whatever organisation structure your tool supports, call it 'favs' and put only 10 brushes in there (medium difficulty 7 brushes, hard mode 5 brushes).

Now draw something with only those brushes. You might find that you enjoy the process more - too many choices paralyze, so try to work with limitations once in a while.
