Financing a brand new 2015 vehicle or Leasing it?

Hi everyone, I need help!
I'm 21 years old and am kind of knew to the whole "buying a car from a dealership" thing.

Right now at this stage of my life, I am working full time hours as a bank teller. However, I don't know where my life will be in the next 3,5,7- years. This is where I'm stuck.

I'm looking into getting myself a new 2015 Honda Civic but am unsure if I should BUY the car, or LEASE it. What are the pros/cons of both? I know if you Lease a vehicle it's technically not "yours"… But what do you recommend for a young girl such as myself?
Like I said before, I am working great hours at work right now, but I haven't decided if I will be going back to school or not in the near future. Would leasing be a better option for me?

Thanks so much for helping this rookie out!
