OK, I'll go.
Each of us will have a unique combination of experience and stage-of-life pressures, I imagine. I took 15 years off from active trading because I was devoting my time to raising kids and also helping my husband build a business. It is fun to be back at it! I joined because I want to diversify my investing style. I'm part buy/hold, part swing trade. I thought it would be nice to round that out with occasional day trading opportunities. Oh yeah, and also, I'm part gambler. A small portion of my capital is set aside to make an occasional, inexpensive, but truly crazy bet. It is hilarious when one of those works out.
QiRa, I say trading/investing is very similar to surfing, which I took up at age 48. And in surfing, I pretty much feel overconfident one minute and very doubtful the next. Kind of 2 sides of the same coin. Over time, I think equilibrium is more easily achieved. Or maybe that's just because I'm getting older....hmmmm...
