I used to absolutely love programming when I was a kid, but got completely bored of it after my first year on the job.

I switched to being a sysadmin, but got bored of that after a couple of years too.

I know other people who've been able to keep their passion alive for decades. It depends on your personality.

My interests change too much for that, and doing something day after day after day for months or years on end just kills my interest in doing that thing.
