It's good to laugh and it's good to be able to laugh at yourself, sometimes it can take you by surprise.
Just like it took me by surprise this evening.
Was thinking about my recent problems getting off to sleep, this is because I can not stop thinking.
While mulling over what I could do to change this I suddenly started laughing as the thought formed in my mind that what I could do was to stop being so critical of myself.
Realised that this is the advice I always give other people, but obviously do not follow myself.
