Quotes like "If you're not prepared to be wrong, you'll never come up with something original"
(Ken Robinson) are not really helpful. A more practical way to see failure as positive is to call it rehearsal. When struggling with a new challenge it does not help to feel bad about the mistakes I make. The purpose of my 1st attempt is to give me ideas about how to make my 2nd attempt awesome. To be honest, I feel frustrated the 1st time I try something new and may even quit. When I was able-bodied I was totally unaware of how often I used both hands or needed good balance so I am often unprepared for the challenges a stroke creates. Trying the task again the next day accomplishes two things. My frustration has receded so I am calmer and the mistakes I made the 1st time give me ideas about what to do differently.
I still get frustrated when I try something new BUT I quickly hear myself say "it's a rehearsal."
This calms me down and reminds me that rehearsal has the potential to propel me to success
if I change the way I think about what is happening to me.
