A chance to see it in action, to practice it yourself, etc. People you respect have told you that you have a gift for it. God has placed them there for your benefit. That is the tangible result of God's hand at work in your life, guiding you where you need to go. Start looking for doors.
Life is like a series of lamp posts.
When you need to know something, God will make sure that you will know it. Your job is to walk to the next light. Use the wisdom and experience that God has given you, ask Him for guidance, and do the next thing that seems right to you. In other words, walk to the light.
