- The stress I must have caused my parents by being a complete arse from about 17 to 21 or so. They had 4 kids with 2 of my siblings suffering from disabilities. The last thing they needed was me adding to their stress levels. Of course, I didn't realise this until after they were both dead and I was a parent of a relatively well behaved teenager!
- Bottling out of trying to join the Royal Marines - trained like crazy my last two years at University but then was too terrified to actually apply in case I wasn't good enough (which I probably wasn't!).
Edit: On a positive note apparently the first thing the young lady who went on to become my wife of 26 years noticed when she first met me was my nice arm muscles acquired from all that training! Also thinking about it going into the forces might not have been the best for the stress levels of my parents!
