I’m a procrastinator… Help?

I’m a procrastinator and I always have been. Up until this point, I’ve been just fine. I’ve started writing many papers at 10pm the night before it was due and I’m no stranger to staying in the library cramming the 24 hours before an exam. Now, I am about to graduate with a bachelor’s degree and have a GPA to be proud of. But I’m getting ready to start NS and I know if I procrastinate in NS, I’ll fail out faster than I can say RN. Have any of you experienced this? I need tips on how to learn to not procrastinate. There’s been several times in my life where I say (and mean it) that I’m not going to procrastinate, yet I still do. Help!
