Strategic accountability
Here's something that's obvious but easy to overlook:
You are responsible for the approach you take to solving your problems, which also means that you are equally responsible for the results you get from taking that approach.
Which means a few other things:
If a strategy isn't working for you (no matter how good a strategy you think it is), it's up to you to acknowledge it and change it.
You may be following a losing strategy because it's conventional (everyone's doing it) or convenient (easier than the alternative). Doesn't matter. It's still on you.
You may not even be aware you're following a strategy at all. You may assume that the approach you're taking and the results your getting are immutable, and that there's no other way to get the results you want. (Alas. Still up to you.)
Self-sabotage is what we call blindly following a losing strategy when a better one exists.
