That might be true to a certain extent, but it should be the same overall. At the end of the day, a loss is something you should just accept and move on, after understanding what resulted in you to lose. It's pointless to keep focusing on something that has basically zero value after the event took place. If we look at high risk investments, then moving over a loss is more easy because of how people in most cases treat their investment as a gamble rather than an actual investment. High risk investmentsl require fairly low initial investments, making it easier for people to treat is as a gamble. It's something I would never do, but looking at the majority of the investment options people have, aside from a few things such as lending, it all involves high risk exposure....
No one became a millionaire at the first attempt, and there was always a losses in the first experiences. But the most important thing is learning from the mistake and trying again, because it will be always better than before , and then the profit and success will be close to you.
