I remember a few months ago started proper trading and I couldn't get around the fact that I lost 140$ in a single trade I was in depression fast forward now I had a loss of 500$ but I was calm. your risk tolerance increases as you trade more
Think about the number of times you've looked at a price chart and said to yourself, "Hmmm, it looks like the market is going up (or down, as the case may be)," and what you thought was going to happen actually happened. But you did nothing except watch the market move while you anguished over all the money you could have made.
