When I said "experience", I was trying to differentiate between a capable person who hadn't done much with one who had been around the block a few times. It's usually easier for the second person to avoid pitfalls and use all of their resources to make a good decision.

Adding experience to a person who is not smart or capable, stubborn, lazy, or has other personality "issues" is generally a waste of time and resources. Looks like you've met a few of these people. Most of us have.
