If you don't "organize yourself" you'll find that you negatively affect yourself and those around you.
You may say "I don't care about that"; but that's not true. You do care... because if you're experiencing pain, you care about that pain - even if it's just in a negative way. claim
Before you ask yourself "what could I do to improve myself" you first need to consider why you should even bother. Two main reasons: First: while suffering may be unavoidable, suffering more than what's necessary is avoidable... so improving your life helps you avoid "avoidable suffering". Second: Your improvement also affects those around you, improving yourself reduces their suffering as well.
