My colleague Brent tells the story of how he got “stuck” at his old job. We were still struggling to deliver the quality we promised our clients, we were using out of date technologies, I went home almost every day feeling down and depressed. I believe “we were still struggling to deliver the quality we promised our clients” is what really wears you down. Using out of date technologies might have held the team back in this situation, but isn’t necessarily the root cause.
It’s ok to be at a place where there’s little or no room for growth, as long as it’s not too long. Watch out, and critically assess your situation from time to time; you might get stuck without even knowing it.
