Hi Ennebe!

One of the reasons Paraliminals are so effective is because they are so organic and personal. You can adapt a Parliminal to your specific purpose, based on what is presenting in your life at any specific time.

Both your alternate choices sound credible, so I think the question is whether you feel your reason for avoiding tasks is more related to a subterranean fear or a lack of focus. If the two seem equally significant, I would suggest trying one for a few days and then switching. Track which one seems to have more impact and do that one consistently.
The saying "the proof is in the pudding" is very applicable to Paraliminals!

Keep in mind, as well, that what works best may change over time. Pay attention to your results, and tweak your listening sessions as needed.

All the best!
