Personal experience sharing

What do you think are the core competitiveness of a good broker?

Do you feel lonely doing business?

Watching trends and doing analysis until late at night, no one cares about losses, no one applauds profits, good or bad, only you know, are you lonely? Do you enjoy solitude?

What books did you guys read when you created your own trading system?

Can retail investors make a lot of money by trading? How can I earn it?

Are you happy doing business?

There is no such question, so I mention it.
