Well you might be correct for Kidd mentality being one of few elements of attributes of successful .......but you can't ditch ppl like Luffy to be losers IRL if Kidd is the example of being successful, Luffy has the same spirit and if not more.
Luffy has the benefits of being the mc, everyone has their eyes on him and due to that ppl helps him, give him knowledge and trained him, and Luffy listened and can put away his pride.
Which is the difference between them
Luffy is the mc and Kidd isn't, the END
IRL, both gets killed in very early stage without plot armor and fate.
