(Not a) Rocket Science: Good Decisions Vs Bad Decisions Vs Poor Decisions
Good decisions - Well thought out and the decision seems to be correct
Bad decisions (there are limitations) - Not well thought out and the outcome is not so great. There are some shortcomings that are outside of your control. You do not have expertise to decide but the situation is such that you need to take decisions. You learn something new. It is failure.
Poor decisions (limiting oneself) - Not well thought out again and the outcome is not so great. But there is a difference here. You had all information at your disposal or you have access to get those information with little to no effort. You screwed it. This is NOT a failure. This is a blunder.
There is a hell a lot of difference between a failure and blunder.
A failure gives you confidence that you will do it after learning and a blunder gives an impression that you lack commitment.
