The world has become risk adverse; for good or ill, it has. We're more careful about the jokes we make, the way we bank, the food we buy, the environment we effect, etc.
As individuals, it has been argued that we are also more reticent to experiment in our day-to-day lives and make a potential mistake. The word "mistake" has often become synonymous with the concept of "disaster".
No one gets it right all the time. No one - if you actually ask them - expects us to get it right each time. Should we be more careful and deliberate with the big projects and decisions that can ripple across many folks? Absolutely! Should we be tiptoeing through our daily decisions? Probably not.
Every week, I try and challenge myself to do try something new: a food; a process; talking to a stranger... often it doesn't result in any great insight, rarely does it give me a rash or nightmares
And regardless of how it turns out, it's ok to make a second attempt. We can't predict the perfect outcome each time; we can only improve on what we've learned from previous attempts.
