In a sense "failure is not all that bad. Some people use it to save money because they were going upside down.
Some people fail at being married cause it wasn't a team effort. Some People fail because they were experimenting and wanted to see the outcome. It's all in how you use failure.
Now success is not without it's failure. Anyone who is great did not get there straight away. There are certain lessons you need to learn that only "Failure" can teach. The trick is in getting back up with your newly learned perspicacity and moving on. Don't ever stop moving.
I say this cause this entertainment industry can be horrid. I've seen people go from the life of millions to homeless and vice versa. The lesson you learn from anything that you "fail" at should be sought so you can keep going. Remember there is only one person in this world. YOU. Everything you see and experience is a reflection of you. Nothing is wasted. If you feel you have failed then look inside for the reason and the solution. Finally know this: YOU CAN DO IT!
