a lot of mistakes with lessons but still keep making some of the same mistakes, i think it is built into human nature
not selling even at 10x profits
buying dabba stocks on tips
averaging loss making trades leading to complete loss of capital (read likes of KS Oils)
getting married to a stock
staying put despite corporate governance issues
buying the momentum but not taking the exit
sure there'll be many more but we gotta learn our lesson and move ahead
