Failure is always an option. This is a statement, and also a quote.

As you said, failures can lead to successes. Do not be so afraid of failing that you never do anything. Try it. If you fail, try again. Well,maybe not skydiving or breathing under water.

How many of the things we use, perhaps can not live without, were not created/perfected the first time. I suspect there was a lot of failure before the success.
