I'm shocked I made it to 20 alive.
Have you always believed you wouldn't live to see 20 ?
Yes, I've believed that for as long as I can remember.
Well here you are! I am not sure why you didn't think you'd make it to 20, people are expected to live well into adult hood nowadays. Try to take a more optimistic view of life, it'll do you some good.
You're right and I'm going to take it easy at this age. I was wrong, whew!
It's cool that you decided to change your perspective to have a positive outlook. Well, it was expected as you have reached the adulthood.
