How do I make myself do something that I really don't want to do, BUT absolutely need to do?!

[BeansCounter]

As per the thread title, I think it's fear based.

Fear of getting it wrong but also, I'm an awful procrastinator.

It's becoming crucial now and will have massive severe implications if I don't do it but yet, I still postpone and do absolutely fuck all.

I frustrate and hate myself. Please give me your tips!

For something like a tax return, definitely break it down into small amounts of time.

I wish someone would tell me how to face root canal surgery, because I've got my head in the sand about that one - I'm just hoping the (two) dentists I've seen are totally wrong, and the "dead" tooth will miraculously just continue not to become painful.
