If you want to be in a program but you don't like working, think of all the benefits you'll get from it if you apply and stuff. :D You're not lazy, Cher. You're incredibly hard working and driven.
You can do this.
I'm a terrible procrasinator and usually end up working on homework until like midnight, but that's just because I don't need a lot of sleep. Oops.
But, anyways. If you really want to get into Advanced Math, just trust yourself and believe in yourself. Put the phone down, set the remote down, turn off the computer and force yourself to work. I know it sucks but it'll all be worth it in the end, babe. :)
