Who am I?

It's a pretty basic question with many answers honestly.

My first answer would be my name, but the correct and more meaningful answer is a bit harder to give. I guess I'm easily summed up in a few words like most people, but you'd have to split it into two categories to do it properly.

First category, what's good about me.

I try to be funny.
I try to be serious.
I'm normally a rather reserved person.
I'm rather blunt when asked for an opinion.
I try to do what I can for my friends if they ask.
I'm usually really creative and try to be patient if someone asks for help.

Second category, what's bad about me.

I try to do a lot of things.
I'm really blunt at times but sometimes skirt around an issue or dodge it entirely.
I use "I" a lot.
I like to put things off until a later time, which I've been working on getting better at punctuality.
I get fixated on things.
I'm stubborn.
I sometimes become really annoying.
I get annoyed really easily by people trying to be funny and watching them fail miserably.
I've got a lot of opinions.
