I think you have a nice future ahead of you. If you work hard in college and in life you'll have a solid career, but as stratos said, balance your work. Work a little and have fun a little.
You're lucky, I got like 13 years before I can be a doctor.
Next four years is undergrad
One to two years out of school for job experience
Then back for four more of med school
then like three years of residency
Then a job when i'm 30 (yay, I hope to get tho this point one day
