You can spend unlimited time working on yourself. I see no unhealthy unbalance in that as long as you have no inner need or outer pressure to produce (or you are able to control both).

Personally I find it tricky, though. Am I doing nothing for this long because I am just getting lazy (-> need resolve) or depressed (-> need real help)? It does not seem to be your case, so just take your time. Take your time.
