I'd say full time, is more of a all your income comes from trading rather than just some, if zero/negative then your just a WIP. 1 hour per day will stop you going insane.
this is a fake and stupid argument. comparing yourself with any(worse) other trader will not make you more money and surely does not confirm that you have a profitable edge. what you tell is similar to saying that you run the 100 yards faster than a man without legs. just compare yourself with the worst possible trader and you will ALWAYS be the winner. but only the winner between you and the example you took. it does say NOTHING about your performance nor potential performance. there are also part-time stressed day traders being pressured to make enough money every day to pay expenses like datafeed... they can also be very stressed because of the expectations to become successful and soon a full-time trader making millions. there are also full-time daytraders that are not stressed at all, most of the real good ones have no stress. depending on your fantasy you can create thousands of different statements, but the only real important thing is: what do you make in real trading? that will never be influenced by the results or problems of other traders. so that's also never an edge. don't look at others, look at yourself.
