How much do you need to know, see, or have confirmed before you make a decision? There is risk analysis, resource determination, physical demands as well the consideration for mental, emotional, and financial impacts. All of this may come within the cost - benefit study that could be quite useful. And there is benefit to consider the spiritual realm; praying for God's will, wisdom and discernment. Seeking wise counsel, Biblical insights and glimpses for what lies around the corner/over the horizon. And if you do ALL of that to a satisfactory amount - it still will require you to have adequate faith enough to take the first step. God always requires a 'first step' to experience the blessings he has for you now! Are you ready?
