Comparing our achievements to others is what makes us regret our decisions even more. We must understand that we have our own timeline and we don't have to race with each other. Not because you've seen someone posted on his social media about getting rich with a meme coin doesn't mean we can also make the same fortune if we invested our money in a meme coin.
What I'm trying to point out is that the more we crave for other's success, the more we suffocate ourselves on making our own path and fortune, therefore we will live trying to copy other's footsteps to success rather than making our own original way on making ourselves successful like them.
This is the thing which people should realize because if we live our own lives and don't think that other is wealthier than us then we will not regret in life. success and defeats are a part of life so we should accept both of them as success can satisfy us and from defeat we can learn and stop to make such mistakes again.
Think that if another person is more profitable than you so may be he use more knowledge and expertise and have used more money than you because positive thoughts can make us successful and in life we will stop to regret on the things we failed to achieve. The main thing is effort not regret because efforts can make you more successful in future but regression can become a cause of your failure.
