Then I would loose my streak and the magic would disappear.

I am not a pro athlete. I think there are many days where athletes go beyond what they should to win some gold medal in some competition.

This is for me only and I am fine with it.

Can you tell me what you think you'd do?

Ya, that's fair, arbitrary motivators are arbitrary, but they still give motivation. I strongly dislike running, so if it was me I think I would give up once I get sick, or likely would not start the streak to begin with. I'm not saying that's the right solution, just trying to address your question.
