Well I consider motivation something that although is influenced by your "environment", you must seek for it. Even with the most boring/stressful/etc. situation, there must be something that makes a little change... For example, my first job was in QA testing, and I don't have anything against it, but it's simply not what I was interested... Initially my life was a little bit miserable haha, because most of my friends were already working as developers. At that time motivation was pretty low to be honest... My solution, I started learning about automation testing, that was more motivating and to be honest, a most interesting branch of testing. There I've found motivation to keep going, getting better and eventually gaining more experience to get a developer job.
