you totally hit the nail on the head. Inner motivation is what i've been thinking alot about lately and am working on (well trying to at least ;o) )
this summer I let alot of outside negativity compound and derail me, and thats when i started thinking I needed a stronger internal base that sees me keep believing and keep going no matter what others are sayin. Propel myself as it were, so totally on the same page as you on that one :o)
Has semester started for you yet? I hope things are ticking along nicely for ya.
