I like to research and thoroughly think things through before moving forward or making a decision. While this habit is wise, if taken too far it indicates a problem.
The problem comes in when we get so worried about making a wrong choice, that we can't bring ourselves to make a choice at all. This is what the Bible calls being double-minded.
But if any of you lacks wisdom, let him ask of God, who gives to all generously and without reproach, and it will be given to him. But he must ask in faith without any doubting, for the one who doubts is like the surf of the sea, driven and tossed by the wind. For that man ought not to expect that he will receive anything from the Lord, being a double-minded man, unstable in all his ways. James 1:5-8
God has all of the wisdom you need to make a good choice. You do not need to be bound by the fear of making the wrong choice. Ask God to help you, then make a choice grounded in peace and move forward knowing that you can readjust if you need to.
