It might not be a one on one coaching, but seeing how much others do while slacking of on the couch and reading about all their doings on Twitter should make you more productive.
I've known people who are perfectly willing and capable mentors, but never got asked. Ironically, they were surrounded by people who were looking for mentors, but were afraid to ask. I happened to know both sides and made the connection, but I'm sure many others fall through the cracks just because they didn't ask someone to be their mentor.
Note: Not everyone has the time, willingness, or ability to be a mentor. But I still don't think it hurts to ask. The worst you can get is no mentor, which is what you started out with anyways.
