Ugh I need inspiration.

I could make any of the specialties work but my problem is a why?  A long term goal.

Biomancy with Cult of the Serpent - Maybe a transhumanist, making people better with 'enhancements'
Telepath - Maybe they're trying to find someone who wronged them and reading thoughts is how to do it.
Diviner - Wants to learn to avoid harm for himself or others.  Dreams of being a general, using divination to help become a tactician.
Also, using divination for research purposes, essentially make a nerd character.
Pyromancer - Maybe a jock like character, flexing his magical muscles for fame and superiority.
Telekinetic - More of a protector type character.  Wants to use his power to shield others from harm, maybe tragedy befell him and he has a constant 'not strong enough' mentality.

I just need a motivation and then I can fit a character around it.  Even something as insidious as getting close to the throne or the pinnacle.  Would I want to make an a hole character though...?

Discussing with someone would help cement my character.
