I think there is a vast difference between saying you pray about choices and try to follow what you think is God's will and claiming that everything you do is because God told you to do it. The second option is far easier because it takes the responsibility off of you and gives you an easy out to justify whatever it is that you are doing. When you quit college and Mom and Dad want to know why, you can just say that God told you to do it. Who can argue with God?
I think that many people of faith, when faced with a choice or a big decision, pray about it. They may seek input and pray about it for a while, but eventually they have to make a choice. Sometimes the choice is between 2 things and sometimes it is a choice to act or not to act, but either way, the time comes and they decide what "feels" right. Maybe it is their gut, or their heart, or their conscience, or even they feel the Holy Spirit is touching them in some way. They decide and move forward with their decision. They strive to be at peace with the decision- which is what I strive for and pray for most of all. I seek information; I seek counsel; I pray. I try to make an informed choice with my values and priorities in place, but I have never claimed God told me. I find that to be the utmost of hubris to claim that one is so perfectly in tune with God as to be 100% certain of what His will is. I try and seek ways to discern His will, but life proves regularly that we all fall short of that aim.
