There are indications that creativity is a potential avenue for you to pursue:
Moon in the 5th; Leo MC, Mercury/Venus in the 7th: yet the intersecting oppositions can set you up for a lot of challenges. At 18 years you have a lot of experience yet to gain. Saturn is apt to be your curse though as it demands patience and time, and while young that can seem like real torture. You are always waiting for your life begin, but this is the time for getting the training you need for the future. Much depends on what opportunities may present themselves and whether you can take advantage of them at any given time...Indeed, your Saturn conjunct Moon indicates that you still have emotional growing to do, for that can indicate problems expressing the emotions...do you feel a disconnect or troublesome relationship with your mother?
Skill alone is not enough for success if you have emotional baggage dogging your interactions with others. All you need do at your age is live one day at a time, and observe what results come from your actions, because it is the things you do every day that will determine your future...thus with patience, hard work and dedication you can meet your goals. In the interim, it can be helpful to observe your charts for every Solar Return, and that will provide a record of your progress and trends for the coming year...
