Thanks for the comment. How well do you think the assumptions need to be rationalized? That's really my issue is that I'm not sure that I can come up with a strong rationale for the assumptions that go into building the model. But maybe I'm just being lazy about it :)
I, too, know exactly where you're coming from with these feelings. I've recently been making incredible progress with changing my thinking to be more productive and to simply becoming more happy and satisfied while moving forward.
3. Work on separating facts from your interpretation. All of us do this all the time. Something happens (an event of one sort or another). We make up a story about that event. We then proceed to live our lives as if our story WERE the event or the fact. The path to liberation lies through understanding that the stories was not what actually happened. We make them up! The reality is always neutral, not good or bad. Just is. And because of that we have the freedom to choose what our reality is. Of course, I'm just scratching the surface, but if you message me privately, I can point you to more resources on how you can work on this.
My point is that if you decide early on that you are bad at something you probably won't spend time on whatever that is and you'll have very little chance of getting better at it. And then you'll just conclude that you've always been bad at that thing and that it's a fact. I like to have the power to decide what I'm good at.
