I wish I learned my lesson to sell and not worry about paying taxes. Big gains can turn into losses so quickly. But it did work out very well in not selling my ESPP/RSUs but it was a big gamble when I decided to go all in instead of selling and moving to other stocks to have some diversification. Decided to put most of my cash into stocks so it isn’t basically just one company. It’s now only about half which is good enough I suppose.
Now I’m going back to increasing cash, buying bonds instead of stocks with any money I save. More diversification but less future returns.
