Lessons
First off, I don't know what you mean by 'circular' and 'specious'
Secondly, I am finding this thread both interesting and informative and, so far, I am enjoying that many are people thinking different things and challenging each other on the variety of perspectives.
Thirdly, the 1,2,3 and 3 points you listed are pretty much exactly what I think.
I find what you did with your charity exceptional. You are obviously a dedicated person with important knowledge and a variety of skills. Thank you for your contribution to our society, I am sure that your community is a better person for your efforts.
However, I am saddened that you had to rely on people selling tray bakes, sponsored cycling events or some poor soul sitting in a bath of baked beans to generate the cash that you need to achieve your outcome.
I am sure if you and I sat together and did an audit on the government (our tax 'donation') spending at the BBC we could have doubled what your group had the capacity to achieve. And you could have had more possibilities and comfort on the road you took to meeting your goals.
Genuinely looking forward to hearing from you.
