Are you feeling stuck in trading due to your strategy? The person you are thinking their strategy is working, may have a strategy that is not sustainable. While it is important to be able to unlearn and learn something you should be able to understand also sometimes that your strategy is not working because you have not gone deep enough in the mastery of it.
So don't you think this point is reasonable enough to compare and learn new things about trading and see what steps you are not taking rightly. If you are having challenges in your trade then you need to reach out to other trader who is doing better in profit that you have seen by yourself. You don't compare just to be jealous but you compare with positive mindset to learn and relearn so that you can be better.
For me, I don't think there is anything wrong with comparing one's trade with someone else. It helps you to understand your mistakes and start doing better in your own strategy or a new adopted strategy from the other trader. There are some benefit in it instead keeping quiet and lavish in losses.
