I recommend reading this: <a href="http:&#x2F;&#x2F;www.sparringmind.com&#x2F;changing-habits&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.sparringmind.com&#x2F;changing-habits&#x2F;</a> and other articles by the same guy.  He links directly to a lot of productivity studies, and you&#x27;re in a good place so you have plenty of time to try things out.  Good luck!
