How do you know if trading is for you?

Trading suits some temperaments and punishes others, and the honest test isn't desire — it's how you respond to the work. If the learning itself bores you, the losing will finish you.

How would you help someone find out?

• the temperament traits that help most
• the early sign that you personally were suited
• the early sign that someone should stop

This thread should be honest enough to save people from themselves.
