Failure is just part of the game my friend. Like all experiences it shapes who we are as a person. I’d even argue we are shaped more by our failures than our successes. Focus on recovering from the failure. Decide if you want to try again with a different approach or if you should just stop. Knowing when to quit is a skill most folks underestimate. Sometimes things are just not meant to be and knowing when to quit keeps you from wasting your time trying again and again.
