I've made good money on the stock market but at the first sign of trouble I cashed out. I remember it as a pretty nervous affair, being up before the markets opened and reading constantly about the companies that I wanted to invest in or had a position in. And being able to absorb considerable losses really helped with the ability to keep moving, if you can't do that then you should simply stay out of the market entirely.

I made a few hundred K and called it a day, the stress was just too much.

The other way to do this is to invest a chunk of your money into an index fund and to keep it there. Buy in over time to reduce the risk.

And then you still have to be careful which fund you invest in, especially if it is in a currency different from the one that you earned your money in - and intend to spend it in.

Oh, and get out when the people around you that have no clue about any of this are getting in.
