When you know exactly what you should be doing, and you know exactly how to do it, then your problem is not going to be solved by more goal setting, "rewards", or blocking websites. It's going to be solved by deciding that you really want to do the thing, and by spending the time to think about why you want to do it, and why it is important.
If you don't have a good enough reason to do something, then why would you do it anyways?
REAL rewards DO exist for many "boring" tasks, but you have to spend time to actually think about those real rewards. You have to convince yourself, and it won't work if your methods of motivation are "tricks." The real rewards are waiting for you, you've just got to spend the time to identify them before you start the work.
