I have seen a good number of people solve this problem by literally doing it - i.e. contribute to an open source project in however small a way, look for jobs which actually do interesting things.

The unfortunate truth is that most people do not have time nor motivation to become a mentor. Even then they will only spend their experience on someone who you could argue does not need a mentor.

It is much easier to find someone who will be willing to point you gently in the right directions in a new Job. There are lots of companies who are very friendly and willing to accomodate one or new newbies. In six months time, you will find yourself in a different place - somewhere better I hope
