Your friendship with this person will make them feel very supported, and you'll actually help them figure out where they want to go in life and how they want to get there. Your normal way of showing them affection will be an inspiration for them, as will your courage, your values and your optimism. If they've been floundering in life, wondering what to do with themselves or feeling depressed or confused, your influence will be even more positive.
You'll understand them well and you'll be able to point out their talents in such a way that will build them up and help them to see the possibilities in their own life. This aspect will create some really good feelings between you, and your close bond will feel natural. You should both strive to motivate each other to keep aiming ever higher.
