Just as God had set Paul apart to be the apostle to the Gentiles, He has a plan for each of us. That plan has been in place since before the earth was created. Besides Ananias, Paul did not consult with other Christians until he had spent time in the Arabian desert. How long he stayed in the desert is unknown, but he returned to Damascus and preached there for the remainder of three years. Then he went to Jerusalem to spend time with Peter (Cephas). Besides what God had imparted to Paul through the Holy Spirit, he was able to talk about Jesus with Peter. That would be a conversation worth listening to. It is also a good example for us to follow. We need to spend time alone with God and then we need a mature Christian to mentor us. We need both to become what God wants us to be. We need to choose carefully and not let just anyone speak into our spiritual lives. After making a careful choice of who that person or persons will be, we still need to verify every word by the WORD.
1 Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world.–1 John 4:1 (NASB)
