There’s some holes in your logic 
Dreams are something that converts into fruitful accomplishments later in life. College is just a tool to achieve a dream. It’s not a dream. Being a doctor, lawyer, engineer, etc is a dream. What you’re actually doing is taking your canteen full of water, pouring it on the ground, and hoping what you see in front of you is NOT a mirage. Smart motivated people are successful because they’re smart and motivated, not because they went to Harvard. You got accepted into a great school. Go and get your education!
