Do what you feel happy doing!

In terms of thinking on a path for your career, think only of whether you are putting all your eggs in one basket. If a job role later becomes difficult to get / stay employed in, and you can't adapt, then that's the most likely problem you'll face.

I have always tried to be interested in a lot of things, so that I can turn my hand to new things once I need a new challenge. It has worked well for me so far ;-)
