Knowing you, I should probably remind you of a few things:
1. Drink plenty of water. Coffee is good and all, but you'll feel better with less of that.
2. Practice your upright bass. And your electric bass. And your ukulele. I know sometimes you get busy or it's hard to find the motivation or whatever the reason is, but you're not going to be a better musician by sitting on your hands.
3. It's okay to fail sometimes. No one's perfect.
4. Take up fencing. You know you've always wanted to and it's never too late try.
5. Ask for help if you need it.
6. Go out on a limb. I know that taking chances can be terrifying, but the good outcomes will outweigh the bad ones by far. I believe you can do it; everyone else does too.
It will be a while before we meet, but I hope that when we do, we will be proud of the people we have been.
