It's perfectly acceptable to rely on your network of friends and associates to connect you with the career opportunities you seek. But they will only send you down the same paths you've already been on: isn't it time to try something new for a while? Don't be hesitant to go down a road that is unknown to you. If you want a change, why not make it a big change? If you are having the urge, that means you are ready for a major transition. Go explore something that excites you.
