Wannabe rockstar

I got this friend (who by the record is not me)

Who wants loves playing his 7-string guitar.

He has been playing longer than I have however, he is blinded by ignorance.

He cant play even if his life depended on him.

Just know this, he has been playing for 10 years just about and still looks like he has been playing for a few days.

He always bags on me and my genre of music. (christian rock) and tells me that I sux and all.

But aside from that.

It looks like he has wasted his life trying to do something he is not meant to do.

He is my good friend and all but this ignorant lifestyle is just not good.

I’ve been playing for only 7 years now and I already am teaching guitar, bass, and keyboard for extra cash. Also, I am in many different churches and playing there and play in two different bands. I’m studying music in college too.

He doesn’t seem interested at all with my offer for help or to even take a class.

He just stays in his room and listens to guns and roses all day but never improving.

So hear is the question:

Should I let him continue on this path or should I try to tell him to stop all together and find a different hobby?
