Ambitious and stubborn...not necessarily a bad thing. After all, you stand in for something you want, you desire, you try hard to achieve it. Not letting it go is all you think about.
Obsessive? Maybe a little... but I learnt from a good friend that obsession is not the apocalypse itself. So why worry about something that seems to be for a good cause? Because in the end you could get disappointed? That you strived for is not what you imagined it to be? Or you fail and do not achieve it?
Everything is possible...but if you haven't tried, won't you be asking yourself whether you might have missed something?
