Below are a few things I picked up along the way in these 30 short years of my life:

1. Although I've been out of grade school for years, I still want to go school shopping every Fall
2. Confidence will sort of just come out of nowhere
3. You'll care about people's opinions less, however, people's opinions will still hold some weight
4. You'll get along with your parents more because you will understand them more
5. You'll realize that your parents put up with your attitude (as a child) far too long
6.  You'll start to say things like, “I remember when…”, and “when I was your age…”
7. You'll despise current music and have an iTunes/Google Play/Amazon library that is filled with music from the 90s and early 00s
