Where you are right now is where God wants you to be right now.
Sometimes we think of our life's unique calling, and we yearn to fulfill that calling that we believe God has for us. That is good, but we must not become so focused on it that we think that our life now is but life in transition, a waiting period for the day when we can 'truly serve God'.
The salt and light of Jesus Christ must permeate. Right where we are now, that is our current mission field. God may have other plans for you in the future sure, but it does not diminish the importance of what you do now.
