What is leading you to believe that where you are is not where God wants you to be at this point in time? What is telling you that you are not already doing those things that God is purposing for your life? If you are dissatisfied, that does not mean that you are not exactly where God wants you to be for a particular purpose. When that purpose has been accomplished, I believe, God will reveal to you your next move and you will not have to wonder about it.
If you decide to step out in faith, it may be helpful to be sure you know what you will be stepping out into. What is it you feel God has purposed you to do? If God has so purposed, He surely will create the way by which it will be accomplished.
I agree with LXF, wherever we are is where God wants us to be for the time He has already established and He expects us to give it our best as if we were working for His sake, which as Christians, we really are. Perhaps, once you have prayed about it and adopted a spirit of "servant" in any capacity that God has so ordained, then you are in the proper spiritual condition whereby more of His purpose will be revealed or attained.
Love, peace and joy in Him
