The above is excellent general advise, in my opinion--and apart from all the details of given cases, general advise tends to be the best one can give in public Forums, keep in mind.
For more general advise of this nature:
Pods can play a great role and fill a unique nich?, in some peoples' lives and in particular peoples' cases, and, within the broader medical community.
But one needs a very clear vision toward that, and a commensurate passion for it, to be truly operating in...in their own nich?.
Imagine: helping people to walk who formerly could not...of all the wonderful things!
If that is you, and if you think you can distignuish yourself amidst the crowd after educating yourself well about it (inculding the debt to be educated aspect, if applicable), then by all means go for it, and with all your heart.
If not, then perhaps keep looking and questing for what is more fulfilling to you.
It is only in that that you will operate in all your potential--there is an almost strict correlation between what you have a passion for and what you will wind up doing excellently in...which is something, simply put, that no one should lose sight of.
