Don't go for the myth or believe that one time is enough. It's not enough to play on one showcase festival. It's not enough to just visit another country once. You have to do it over and over again.
Same with meeting people. You have to meet them several times before you do business with them.
It's not enough with one release it has to be several.
You always has to prepare to do things several times. Do it over again, and reinvest in different projects. So when you start have a budget that actually supports to do it several times. Do it once and you can probably skip doing it.
