If I knew then what I know now...I'd get all the lottery numbers right, every time. Unfortunately, there is no going back. Most such observations made with the benefit of hindsight have little or no practical value for the same reason that we probably shouldn't feel too prescient just because we are watching a repeat of a television program and know how it will conclude.
I think that a better question would be, What might you have done differently knowing exactly what you knew then, not now? What might you have overlooked that perhaps you should not have overlooked at that time with the information available to you at that time? That is something you can learn from going forward. Then the regret, if any, need not be gratuitous. (Even so, I imagine that regret is seldom ever a good thing.)
Against this background, I wish I traded smaller when I first started. I had no business trading the relative size that I did with the "knowledge" I had then. I should have known that then.
