My dad won prizes for art and poetry at school but he never did anything with it. He was offered a place at a prestigious training institution in England but he didn't take it. He had potential that was at one time almost unlimited and with the years all those possible bright pathways narrowed down to the one that was his life.
That in itself is not a bad thing. He had a good life. He travelled a lot. He saw much of the world. He spoke 4 languages. He was able to spend time reading. He had a son and a wife and a house and careers. He achieved a lot of good stuff. I think he helped people too.
We all make mistakes in life and none of us are perfect. We can all, always reflect and we often realise that we could have been better or done things differently. We should not regret though. If you must regret something, it is better to regret something you have done than something you haven't done. The space between thought and expression can last a lifetime. I'm mixing the wisdom of the Butthole Surfers with Lou Reed but both are true.
I miss my dad. He wasn't perfect but he was my dad. He had some gifts and some talents.
