How do you really decide between two passions?

I've been to college more than once and each time changed my goal.

It's always medical, towards being a PA or doctor (don't want to be nurse for a few reasons, plus already a CMA). Since I was young medical has been my biggest goal.

I've done criminal justice which..... fascinates me but not much interest. Seems traumatic.

Lately I've realized a passion for daycare. I've taught before but never thought of it as a career

Maybe a PA who goes into pediatrics? But that brings a whole host of extra sad possibilities. Idk.

How did you pick your end result?
