Now that I'm single I have all the time in the world to focus on myself.

Better social skills: more eye contact, smile more, better listening and feedback, be more interesting, better story teller, K.I.S.S., be a better friend to those that matter, be a better family member.

Better habits: self reliance, attempt to be cleaner/not make a mess, healthier (workout more often), study, be more knowledgeable about different areas.

Change the world by changing myself.
