These are a few of my favourite things
There are some people I meet who approach life in a way that seems to bring them maximum satisfaction. I have often wondered about how this happens and one thing that they do have in common is that they seem to know what they want in life, and by and large have a life that meets their desires. I always feel a touch of envy as there are a lot of 'adults' I know, myself included, who are still not sure what they want to be when they 'grow up'. That said, I am fundamentally happy and count my blessings regularly.
One thing that strikes me about happy people is that they are often, maybe not quite selfish, but they do have a healthy regard for their own needs. None of them are suffering from martyr complex and always putting themselves at the end of the queue and expecting nothing for their efforts. They place a value on themselves and don't let anyone take them for granted. They are well able to say "No".
The older I get the more I realise that you have to keep the past at arm's length. We all have regrets. The only people who don't make mistakes are people who don't do much. Everyone has failed again and again. You can learn from these things without having them dominate your every waking hour. Neither can you live for ever on past glories. I always watch for my sentences beginning with "When I was xyz" or "when I used to…" because usually the person listening has heard it all before and is glazing over. The past will be a straitjacket if you let it. I prefer to live in the present and look forward with a positive attitude.
