I think it depends on the person itself because if they have determination to learn and to be a successful investor then they will look for some ways to enlighten themselves so that they can make the right decision. Investing involves taking risk that is why you need to have a enough understanding so you can face any problems and handle things very well since there is no assurance that the outcomes of our decision will always be positive. Like for example here in the forum, people gives and share their own knowledge to give us a better understanding for a lot of other things, you should just open yourself for new learning because it's already there and you just need to acquire it.
