Teenagers can't wait to grow up...and that includes becoming 'serious' with their boyfriends and girlfriends. But, in later life, those same people often regret that they didn't date more people before the got married and settled down. Date a lot of people while you are young. You meet a lot of very different people and learn the great thing about those differences. You will never regret dating a lot of people when you get older...but you may regret dating just one or two people while you were a teenager.
