There's an old adage about the stock market that says you should 'sell and regret'.

What they mean by that is it's better to sell, take the profit and regret it because it would have been higher if you hadn't sold, than it is to not sell and regret it because you need the money and are now force to sell at a loss.

So I do, sometimes, sell and regret.

I regularly try and pocket some of the profit, otherwise what's the point of investing.

Or least that's how I see it. But anyway, two days ago, I sold all my Tesla shares, because Tesla was worth around 20 percent than when I bought it.

I sold at $214.

One day later, it reached $234.

But I have no regrets.
