I do think you have to keep "trying things." Trying to do new things. Or, I guess I mean, you should keep doing new things. It's something you learn in the creative realms, which for me would be theater and music. You are always searching, testing, and performing and then moving on.
Lots of ideas blow up, or fall flat. Or outright fail. That's part of the process. So yes, failure is an occupation. But it's all the little failures that show you the way. And you can apply this to any realm in your life. You wear failure like a cloak. Don't take it personally. Run the idea to it's conclusion. Test it, see if it flies. Most times it doesn't, but once in awhile you will be surprised. There is life in a new idea, a new venture, a new attempt. And that brief success is worth the trouble.
