(Not a) Rocket Science: Good Decisions Vs Bad Decisions Vs Poor Decisions
Good decisions - Well thought out and the decision seems to be correct

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.
