We all fail at times, the question is how to respond to this. Sometimes we fail to do/achieve something that to be realistic we aren’t going to ever master for whatever reason.
Many other times we may feel like we have failed, but actually it’s just a learning curve and it’s soon time to make another attempt. The next one may well lead to success.
Failure gives me another opportunity to try again and if necessary do things a different way, and will eventually lead to success. Failure teaches us patience and determination pays off.
Life would be boringly predictable if we always succeeded first time. Where’s the fun in that?
