GJ was to the point of taunting death to come closer, even sometimes asking for it.

Mark is kind of bragging about how much he has helped GJ, and how much he intends on helping GJ in the future. He is saying, “You know I’m here now. I’m going to help you through this (which he did) and in the future I’ll be there again, whenever you need me.”

Mark is telling GJ to attempt anything even if others say you can’t. They say you can’t rap, keep doing it. They say you can’t make it to the moon, turn into Neil Armstrong. R.I.P.

Even though he just said don’t be the coolest, you still have to have that sort of confidence with a touch of cockiness. The coolest person that you know has to be yourself.

Mark is telling GJ, be outgoing! Be fun! But you don’t have to be the most popular. You have to be happy with what you got, and see the good in things.

GJ’s depression got so bad, he couldn’t make or write any raps anymore, which was one of the main reasons why Mark made this song.

GJ had trouble sleeping, all he had were his thought and memories and he couldn’t stop going through them at night.

The girl GJ loved recently cheated on him. This brought up so many feelings, he can’t hide his pain with a simple smile anymore.

Mark will always help GJ, when the odds don’t seem to be in his favor. Like this point in his life where he’s at his lowest.

If he would quit being mopey and depressed, he wouldn’t fear talking to others and be outgoing. This will help GJ in many things, such as finding a women for him.
