When did you get old?
At some point, most brands, organizations, countries and yes, people, start talking about themselves like they're old.
"We can't stretch in that direction," or "Not bad for a 60 year old!" or "I'm just not going to be able to learn this new technology." Even countries make decisions like this, often by default. Governments decide it's just too late to change.
The incredible truth is this: it never happens at the same time for everyone. It's not biologically ordained. It's a choice. It's possible to put out a hit record at 40, run a marathon at 60 and have your 80 year old non-profit change its business model. It's not as easy as it used to be, but that's why it's worth doing.
The other thing I read recently was, as you get older, you tend to spend more time thinking about the past. This is a clear trap - not only is it a waste of time, but it can also lead to regrets, and guilt, baggage we can do without. Something in my nature/nurture means I don't go here, which is wonderful.
