you won’t be able to do alot of things you want to do
you can’t sleep alot
you can’t eat what you want
you can’t see the people who you miss
visiting your loving family, dating and many other things that you want to do
you have to change
you give all that and receive the opportunity to be a singer
you have to give up a lot for a long time

Do you still want to be a singer?

But when you stand on stage in front of thousands and they applaud for you
all your difficulties and lonelienss will go away
all the troubles in your heart will all heal from the applause
