This doesn't work for me or probably some other ppl. My brain's attention would be dragged to the consequences and still won't do the work.

What I find useful is the vomit writing technique. I will just drag myself to get started no matter how horrible the work I am doing in the beginning. But once I started doing, I won't feel so bad. This basically solved my problem.

I just need to start doing and do a shit job, then improve it to be less shitty.
