Optimistic, with a sunny disposition if you don't mind puns, you don't mind handling things in a way that's fairly straight forward rather than overly complex. That's not to say you aren't capable of more complicated scheming, but even when you're playing the chess master, you keep what you want out of life in sight, and are always moving in that general direction, even if it's not immediately obvious to the people around you.
You want to do your best for the people around you, and you have no problem asking for help when it's needed. However, sometimes you can over estimate your own strength, and a Sun on a darker day can be a little guilt ridden. You're always eager to prove to yourself that your way is the right way, and sometimes you can be left trying to fill in the holes for things you overlooked, feeling that mistakes aren't worth accepting, no matter how old they are.
