You must go beyond your goals and pin down the traits and characteristics they stem from. Are your goals realistic? How do you regard money? How do you handle it? Are you easy-come, easy-go or do you count pennies? Are decisions involving money difficult for you to make? Are you on top of your budget or always running to keep up?
These are generalized questions and there are no absolute answers. Speculators should stay out of the market, but on the other hand, being a tight-wad is no virtue either. An overly cautious or conservative temperament may not be well-suited to react to the ever changing market conditions and thus miss out on opportunities to sell or buy.
The value in knowing thyself and how you will likely respond in a variety of financial situations is vital. Any personality type can count profits but it requires a certain rigor, a certain fortitude to face up to the adverse situations that investing unveils. If you have a character flaw, losing money will quickly expose it.
