How would you make money ?

the second one can be mastered by technical analysis.

That's an open question, but I lean heavily towards the theory that any pattern that becomes known to be profitable is no longer profitable.

E.G. if there was a pattern where you buy on a Friday and sell on a monday, and make a profit, as soon as it becomes known, people will do it until it no longer becomes profitable.

If you are still interested in day trading you could have a go with no risk by manually recording what you would have traded (without actually buying/selling) and see how you get on. (I did that for 18 months before I got into the stock market.)
