You two will add a lot to one another's lives and provide guidance and support to the paths that each of you choose to follow as individuals. You'll find that you're really in sync; what's good for one of you will be good for both of you. You'll have a nice influence on your friend, offering your support and encouragement for all their efforts to move forward in life.
You'll act as inspiration to this person; any act on your own part to realize your own dreams will be an inspiration to them, because they want to follow theirs as well. And when they do go after what they want in life, you'll feel inspired and more driven as a result. Your generosity and support for your pal will make them feel armed and ready to take on the world.
