How can I keep myself accountable and stop procrastinating?

Try to think of what is the most important thing to you right now, and do you really need to do it? If not, think of something else. Or if you want to do something, think of the benefits that it would give you.

Tell someone else about your goal and have them keep bugging you until you actually do some work.
Just start, an author who wrote 70 novels was asked how? He replied 200 crappy words a day, the act of starting will help you take action that inspires yourself.
