It's a weird thing to say but the longer you've been at a company the more you're "part of the furniture" and your shortcomings stop mattering as much to your co-workers because you're, well, part of the furniture. If you want to grow and push yourself you're going to need some new coworkers. It may be uncomfortable but it's worth it in the long run. That's not to say it's a guaranteed win. As all things, it's a risk.
