" A musician must make music, and an artist must paint, a poet must write, if he is to ultimately be at peace with himself." Abraham Maslow
Get over trying to be unique. You are a mashup of all your experiences and ideas and every person who has been important in your life even the bad ones.
Intimidated by a blank page? Write down a line from one of your favourite songs and then write about the images it brings to mind. Look at the feelings it stirs up in you and write about them. Draw a picture, the only one that is going to see it so use stick figures if you want. Try your own hand at writing a verse or two or write a whole new song using everything I mentioned before.
Don't quit too soon! Take the whole day or more if you want to.
