If you are middle aged and have many years of experience, would you work for a teenager? Probably not, right? Huge career risk perhaps, and their lack of experience means you may not learn much. Besides, working for someone that much younger than you could be a bit weird.
That thinking is passé now.
No I’m not saying this frivolously.
I recently discovered that one of the hyperlocal apps that I use is a billion dollar company run by two teenagers!
Of course no one can see the future and how risky it can be. But surely in this day and age, age is no bar. Execution of an idea (perseverance, patience) trumps everything else. Good advice for spirituality as well.
