Veterinarian or not?

I realised I've reached the point where I question myself day in day out, before I sleep and the first thing in the morning. Is it going to be worthwhile doing this? Study painstakingly for six years, graduate and work crap hours and still get shitty salary. All for the animals, and the world is still unchanged. I pop myself another question again, how much have veterinarians revoluntionised the world?

There must be a reason why veterinarians are always in the background compared to medical  professionals. Why is there only one Nobel Prize winner as a veterinarian, for as long as the nobel prize started? Are we lacking something, or are we overwhelmed by what nature and wildlife can offer us?

How can saving animals ever be compared to children being abducted everyday, young girls being snatched away in their own village and sent for slavery and prostitution, children starving because they don't have enough rubbish scraps to feed themselves? Outcries from the public when they see a video of animal abuse, and even so demand immediate political action, especially in developed countries where the people are living comfortably with little to worry for. No one mentioned a single word when we hear news of girls being snatched away, or children starving in developing countries.

I'm halfway there, is it too late to consider giving up? Anyone who could offer me a way out of this, I would seriously consider my options. Forget the honour, forget the prestige. It's only worthwhile only when you work to live, not live to work.

Let me pray that the A$300k in exchange for medical knowledge will allow me to change the world.
