Take out the comma after girl. Usually, a comma is only added when you pause during the sentence, and it usually is followed up by a transition (although not always). The sentence, "I'm an outgoing girl who likes to make friends," is a sentence that can stand by itself, without a comma. Sometimes needs a comma after it because it a transition (think of transitions like First, or, For Example,). Take out would too. (Sometimes, I act...). Would is past tense and you are describing yourself in the present. That sentence afterwards is weird too.... Mainly because I can't translate what you mean by "with a little bit of clever."
Take out the comma after everybody and forgo the word "so" and make a new sentence with "I'm everybody's clown, who always brings laugh and joys to people everywhere."
It's okay, but it needs lots of work. Try re-reading and re-wording. Good luck!
