My parents (perhaps foolishly) allowed me and my best friend to buy chemicals at age of 11. I had a mentor at church - an industrial chemist - who at 23 took us to a small chemical supplier and introduced us to the owner, saying “you can trust these lads. They know what they are doing”. Fortunately, our attempts to make nitroglycerin failed spectacularly. At the age of 14 I realized had we been successful we would have had a six foot hole at the back of our garden. Didn’t stop me blowing the roof of my Dad’s shed though, with a hydrogen balloon gone awry.
I let my son at 14 spend almost all his further education fund on a high spec desktop and high speed recording system (predecessor to streaming technology) because he said he could make a business out of it. He did not get to the business level, but appreciated the support from Dad. One of my mentees won a competition in the UK with his Dad (an accountant) because his father let him trade stocks on the FTSE, under his mentorship.
Some of us are very lucky. We have Mums and Dads who let us loose and find out the hard way. Most are “sensible” and don’t want their offspring to experience any sort of risk in the real world. I am so glad my parents were who they were. I consider that I and my siblings were in the lucky 1%.
