Christ, I could write an essay on why Catie is so awesome, but I'll try to keep it concise...
To me, Catie is a very remarkable person. After all the shit she's been through, she's still wonderfully positive. It's like it didn't change her at all. That speaks volumes about her strength of character. That positivity seems to radiate out of her like she's some kind of transmitter mast, and it cuts right through to your core. It's not difficult to feel energised or 'charged' by that positivity. Like, if you're feeling a bit flat, a bit miserable, all you need is a bit of Catie Wayne and everything is right with the world. She just helps to remind you that no matter what crap might be going in your life, or in the world, there is still a little bit of good out there that seems unshakable.
Not only does she seem untarnished by what she's been through in the past, but she's also very kind, caring & friendly, accepting of anyone and their differences and treats everybody equally. She's the kind of person who, no matter who you are, will make you feel unreservedly accepted and not judged for being you.
She also has lots of charm, intelligence and wit. One can't ignore her seriously good looks, either.
Her nerdiness/geekiness is something I think a lot of us appreciate, too. Coupled with the fact that she's totally not aloof in any way (like most vaguely famous people are) and is really modest and self-deprecating, it makes her really accessible.
Finally, when was the last time Catie was seen to be hateful? I don't think it's ever been documented, and that says a lot. She's just really loving, all the time.
She's a great role model, and I feel like she motivates me to want to be a better person, and to keep improving on who I am.
Did I cover everything? Probably not...
