One of the things I have tried to teach by staff, teams and people I mentor is to have a go and learn from failure.
Life is a journey and the process of improvement is to iterate and improve with each cycle when you come across a problem.
As Edison said I learnt 10000 ways how not to make a lightbulb.
Creating a safe environment to fail is critical, put the padding or bubble wrap on the floor so you don’t get hurt when you fall.
One way managers help their team is to make sure that the consequences of failure are not so big that the pupil loses confidence and self esteem but be challenging enough to extend their ability and grow.
