I get this sometimes. For me, it takes the right balance of something I'm excited about, having a lot to learn, and having drive from people whom I feel are pushing me in a direction that's better when I'm having trouble ramping up, but not in the way when I'm really rolling out code.
I've been doing most of that lately, though I can get into a dream state quite a bit where I want to make something really awesome that will slow things down a bit too far.
You're really lucky people are pushing you. I'd love to have that! Some of us are less fortunate, either because other associates are not interested in the projects you're working on, or because they're super busy in their own.
I don't get a lot of friends and associates asking about my progress, but I always make sure to reach out to them every so often to see how they are doing and offer myself as a resource if they need it for anything.
