OK, if you just would like to make crappy FX-movies like Transformers or stupid games like Crysis, here is my quick and completely honest answer: reconsider it!
You could do a lot of more useful things.
You could be a teacher, a doctor, a policeman, a fireman, a researcher, a scientist and the list goes on.
These are more important jobs, if you think globally.
OK, maybe you feel some disturbance in the Force right now…
You are right.
