I loved maths but life as a mathematician was very depressing. Another point I would like to add is that there are very few mathematicians compared to biologists. Actually, I am not very sure if it's true in the US and Europe but it certainly is in India. The biggest of math conferences here have a 100 or so people and so do the smallest of the biology ones.
