Without being informed we can't create wealth, the opportunity to be wealthy can be right in front of some people but because they're not Informed they missed it. Bitcoin is here to also help us create wealth by investing and hodling, but for those who aren't informed, they're going to missed it and that's just how wealth can be created or missed. Lets look at the people that were fortunate to know about Facebook shares and other big companies shared bacon the days, if they weren't informed and didn't have available cash to invest, they would had missed that opportunity.
Here you're talking about when you get disappointed from a previous investment that didn't turn out as you planned then you need to channel that negative energy to a positive one by picking yourself up and trying again. Wealth can't just come from one try, you have to try many times before you finally get it right. Like the wise saying goes "if you want to be a billionaire, you don't have to be afraid of losing millions". By protecting yourself from losing by not taking risks, you're setting yourself up for failure.
