Staying focussed

Watching Spooks last night on BBC1 it made me think about staying focussed and achieving the things that God has called us to do. The Spooks team were faced and are regularly faced with hard choices, difficult situatins, and even times when it is possible that they may have lost members of their team, but through it all they remain focussed on their calling. How easy is it for us as youth workers to remain focussed upon what God has called us to do and be? do we put things in place to ensure that we can stay focussed, because it is those who stay focussed who will achieve the purpose that God has claled them too.
