For those who profit with stocks, crypto and other assets as other means of income. The most common regret is not having started earlier. Time spent idle could translate to opportunities missed.
There are some who believe the biggest danger is taking a chance. They play it safe. Not realizing not taking risks, could be the biggest risk of all.
To be honest, this mindset can be pursued and of course has different effectiveness, if we always play it safe and make it seem more comfortable it will create a point of stability which will lead to stagnation in entering and exiting finances and it will take a very long time to reach the point of success, different it's the case with people who take risks from the start, it may seem like gambling on their way but have a very dense fruit of experience which can help grow a mindset in executing the next opportunity and this process is much faster to change fate for the better (but if we can learn from every mistake.
In conclusion I'd rather take the risk early than miss the opportunity, even though the success ratio is 1:10 it's much better to learn the lesson sooner.
People say that big risk is seen from what can be lost when experiencing failure, but they don't see much knowledge provided by a failure that will make us better in the future.
Maybe when we start taking risks we will definitely fail in the process, but if we just keep quiet it is certain that he will fail before going to war.
Paper profits are not real. I have gotten huge profits but in most of them didn't sell until these profits went bust. Imo, this way sadder than regrets mentioned in op, because here money comes to you and you turn blind eye towards it. I still have sleepless nights over amount of money I've given up by doing nothing.
Yes, we often encounter this behavior from most people who regret after investing who think that even longer they will get more profit, and after a while what makes it profitable turns out to be a loss because it holds on too long and continues to hold it so that regret is the final result because what he could sell is worthless due to bankruptcy.
