Mate

There are people who are 40 years old who don't have their life set

You know how to work hard

You know how to fend for yourself

Those are incredible skills that most 20 year olds don't have

And dude you may feel like you're old at 20

But you really aren't

You have your whole life ahead of you

You'll get through this
