The problem is this shouldn't be a gender-based problem but a personality-based problems, because despite what study says, even if the majority is more risk taking, there's still a lot of mans who doesn't take risks. Don't forget that if 60% of 150 million of persons get it right, 60 millions of it get it wrong.
Also, I think deep inside the right answer of the question "Should I go for it?" is there. The problem is to listen the deep inside. Finally, I would say that the bigger & better risks you take, the better benefits you may get.
