In this day and age, if you're aspiring to be an actor, and you're putting all your eggs in one basket, you could be disappointed. I started out as an actor, but I forced myself to be a writer, even though I wasn't very good at it and had never written. I don't think I ever passed an English course in my life. My first 8 to 10 scripts were pretty horrendous, but I stayed at it until I eventually found a voice and a subject that people were interested in. So, I recommend that you go out and try to be as versatile as possible: writer, actor, producer and especially director.
