The good news is you have identified that the key art of trading is taming your own psychology.
The bad news is you probably have a long way to go. Trading depends on capital. The science of trading is about building your capital and about protecting your capital. That takes time and experience.
No argument here, I want to grow the money I have already put in rather than continually adding more. And that's another area of discipline because I need to have more patience and not get distracted by the next shiny coin. Thanks for the comment.
