personally, I believe that front-end /web/ development is the most personally rewarding field to work in. Especially so if you are delivering for wide-reaching or large clients.

I take such joy and pride in being able to build tangible tools and/or visual components in collaboration with great designers to produce work that is used and actually /seen/ and interfaced with by millions of people.

Also, tapping into my OCD side; I have a love for perfection- and I get to exhaust this love day in and day out in the everlasting X-browser css/js battle that front-end is.
