I've been investing for 30+ years. Chose to make the stock market one of my hobbies. Learned how to invest to minimize taxes when I retire early and get free health care at the same time. The downturn in the market now is normal and it's a buying opportunity while everything is on sale.
This "hobby" already allowed my wife to retire at 60 and as soon as hit the same age I'll retire as well. I should be able to spend about twice what I'm living on now and still continue to see an increase in net worth.
Needless to say I'm a big fan of the market.
