It sounds like people who invest the time to properly learn finance can make a pretty good living at it. If that’s you, I wish you the best of luck.

But I’m a retail investor, and will almost certainly remain one— Not only do I not have the training to come up with these strategies, I don’t have the knowledge to judge the veracity of anyone claiming to sell them to me either. I’m content with my suboptimal portfolio that I don’t have to think about more than once a year, and have more important things to spend my time on.
