Do it! Life is short, you don't know who you could meet out there, the endless opportunities you may stumble across, life is an adventure, don't sit at home envying other peoples courage to explore and live their life, go out there and live it yourself! That's certainly what I intend to do! Don't get to 30 and look back and be wishing you had done it! Do it now while its on your mind, it'll be the best thing you do! I've been to Australia and I CAN.NOT.WAIT. to go back!
