I'm 21, I used to dance and want to again next year. I used to be one of those people who enjoyed being single and shook their heads at people in relationships. Now I am one of those people in a relationship, so past me would shake her head at present me.
I didn't tell past me that I was in a relationship, though. When I time travel, I have a strict rule not to change anything. Something I considered a mistake in the past might not have been a bad thing. If I were to change it I might end up somewhere completely different - or even worse, someone completely different.
