Taking risk is very crucial part specially when we don't know the outcome of the risk that we take. Sometimes we failed and sometimes we loss but only one thing for sure is that we gain experience everytime we got failed or everytime we loss, if we don't take risk we cant earn big profit we are just like an investors that has so many regrets in the ends in my own opinion i think taking risk is the key to improved.
I think that if we don't know the outcome, we are afraid to take risks but if we do know it, and we know that the outcome is mostly positive, we will be ready to take risks. Not just losing but winning or profiting can also give us an experience and the experience can be more, just like when we play a video game where we are also being rewarded with more experience once we defeat our opponents or if we successfully completed a quest.
In life, all has a risk but there are still poor people. If it was about taking a risk, investing in assets like Gold and BTC, then losing is also possible. Money isn't all anyways but poor people can still be able to regret. Regrets are normal and still shapes us. It must have a reason on why it occurs. So, I won't totally beat myself up.
