Believing in a destiny or fate like that is also quite healthy. You can just sit back and relax. Better than feeling like you have to force yourself to do it.

It also diminishes the anxiety caused by you thinking you've lost control: you never had it in the first place.

There are better and worse belief systems. Basic assumptions matter a great deal. Assume everything is possible and you have no say in the matter whatsoever. A beautiful paradox. Must be true. Your rationality better be flexible.
