Swamped by trivia

I have realised that my email life is becoming too busy. I realise that I have subscribed to too many mailing lists. In the last few days I must have unsubscribed from at least 20 lists. Instead of a stream of emails during the day I only have mail from 'important' people. It is amazing how easily one is pulled into the flood of unimportant bits of information from book shops, cinemas, special offers, technical news, teacher news, etc. I was being swamped by trivia. Do others feel the same?
