I feel like being productive?

I want a job, seriously. I want to learn about scholarship opportunities. I want to save money. I want to volunteer. I want to lose weight. I want to do good in school. I want to be productive.
My dilemmas?

1. I want a job, seriously. -I'm 14. Nobody likes 14 year olds. They think we're immature :| Well, I won't lie, most 14 year olds are.. and it sounds so young, I assure you that, But I act and feel much older.. Eh.

2. I want to learn about scholarship opportunities. -Again, I'm 14. There aren't any scholarships open to 14 year old freshman's.

3. I want to save money. -We come back to the age problem.

4. I want to volunteer. -Outside of key club, I don't know how or who to talk to about that.

5. I want to lose weight. -Yeah, well, that's a self-problem.

6. I want to do good in school. -This year, it's all pre-ap. I do the work, it's turning it in that's the problem.
