I'm 13 years old and want to be a actor any ideas how?

I'm a 13 year old boy and am interested in acting and drama, the other day I was thinking about how much I like acting and drama, so I was thinking how can I get a job on T.V, whilst I was thinking about this outnumbered came on and I thought, even if I was in outnumbered I would be happy, any ideas how I can get a job like that? Any ideas? Thank you. :)
