The losing version of me would start trading without creating a plan then proceed to invest in majority of my money all at once. then if it fails I would give up.
The winning version of me would plan to research stocks that I am interested in then buy and no matter what happens hold for the long term.
a winning action I would do would be to research any stock that interests me.
what I have personally done was started looking into ETFs that would be best to buy.
