First, it takes three months to understand a new job. Until those 90 days are over, you don’t really know what hand you’ve been dealt. Second, it takes approximately three years before you’ll become bored with your current gig.

Interesting article from Michael Lopp. I never really thought about it like that before, but maybe that’s because I’ve been doing the same job for 20 years.
