Search deep inside yourself and do some soul searching...The answer will come, in time.
...If that fails, you could always be some strange/unique/awesome hybrid...
i don't think you can refer to picking a fursona as soulsearching, as that can take several years to do, whereas picking a fursona is more like just picking the animal you like most
Not nessesarily true, for some your fursona can be a very spiritual thing.
spiritual or not, i've been trough a soul search, and i can safely say that picking a fursona doesnt require one (fyi, my soulsearch took 3-4 years to get somewhere, and another year to refine my findings) oh, and plz dont ask me what i came up with, its not something i spread around like some kind of fad.
