Jean Grey manifested her mutant psychic abilities at an early age, and was subsequently sent to the Xavier School for Gifted Youngsters to learn control over her powers.Marvel Source
As a founding member of the X-Men, she's spent most of her life as a hero and has the calm confidence of a seasoned pro.

* Cybernetic Implant, +807 dam when you drop below 25% spirit: since Phoenix Drain eats spirit, may as well get a benefit out of that

Also, DuNAstES points out he's limited Phoenix Avatar to 15 points because that's the max force gain benefit; that means getting 2-3 points from it to put someplace else if you have a medallion or the Idol of Konshu.
