You rock up and you don’t have everything prepared. Just some fresh enthusiasm and a healthy attitude. When you are about to start you see other people do things differently. Do you leave?
Unless you are confined by some strict safety codes, find a way. It could be as easy as spending a little bit of money to get what you need to be normal. Or why be normal? Be awesome and inspiring. Find other ways that may not have been tried and participate.
Conforming is the safest route and also the most numbing. Live a little and try it your way anyway.
