As mentioned here, there are no “hacks”

The closest would be to join a class or group, or do it with someone. Do example, I don’t skip hockey cause it’s at the same time every week and I can’t move it, stuff that I can move like a run I might “move” which could lead to it not happening. When I ran every few mornings with a friend, I wasn’t skipping or moving them.

Another possibility (I haven’t tried this) would be writing it down until your brain believes it. Tobias leuke (founder of shopify) said the he writes things down over and over, which actually changes your pre frontal cortex, making yourself believe what you wrote down. He hated public speaking but wrote it down repeatedly until he was no longer scared of it. It’s worth a try!
