I found in my 40's, I questioned..."Am I doing anything really important with my life?". In my 50's, it became more..."Let's just do the job as well as I can". Now, in my 60's it's "Who cares?". I guess having gone beyond my FI number helps. I definately sit back and laugh at things that used to bother me. My company tends to spend great, inordinate amounts of time naming things. Some spiffy name MUST be found for an upcoming sales training meeting for all the US. Speaking to my boss's boss one day, I said to him, "you know, it really doesn't matter what you call it. At a former job in a company 20 times our size, you know what they called this kind of meeting? Sales Training Meeting". He was unamused and I didn't care. I still work here.
