Playing different songs is cool but when I play in the street I'm doing it to make money. You'll find that 20% of your songs will make 80% of the money.
Finding places to play that you can just play those songs over and over will get you the cash and you're in and out without wasting your whole day.
The 20/80 rule applies to almost everything and I wrote more about that with a link in this post to that story.
Thanks for checking out my post.
