It's okay to fail. I'm in process of working out the first vlog that I've ever made and I have been able to fearlessly approach the process by learning to love the process and letting the process itself be the goal. If the final result is a failure, that's fine because the goal was to complete the process.
When the process–the learning experience–is the goal, just making it to the finish line is a success. If the project fails at any measurable level beyond that, it's okay. You've already gotten the benefit and next time you will be a little better and the time after that will be even better than that! Keep going! Don't let a little failure hold you back.
