Both. enjoy being young, but also prepare for your future! You can do both at the same time. Talk to you parents, ask them what they would do if they were still in their youth and make sure you complete it before you're too old! Don't waste your youth. Don't waste it caught up in the things of adulthood, but also don't waste it being a child and ignoring your responsibilities, you'll regret doing just one, take advantage of this once in a lifetime experience!
