The best route, in my humble opinion, is the combination approach e.g. fisherman by day, and EOD swingtrader in the evening... Or for that matter, any vocation (e.g. fisherman, musician, athlete, university professor, detective etc) that you are passionate about by day... and trading, which you are also passionate about, fitted around your vocation either: 1) opening market plays if you are on the West Coast 2) EOD swingtrading if you are on the East Coast 3) Intraday trading of last 2-3 hours if you are, say, in Europe By doing both you are not reliant on either, and you fulfill two dreams simultaneously...

but then the family can sue for compensation for mistreatment (discrimination etc) and live in comfort happily ever after....And they'll be able to bring their extended family over too.... Sherlock
