I follow Timon and Pumba's philosophy of ... "a'kuna ma tata" ... got no worries. Sometimes I am on time, sometimes early, sometimes late. If others who are meeting me are late it is no bother to me at all ... I have something interesting about watches to read with me at all times. Cell phones have made life very easy for me. I think that it is my personality to not to take myself and others too seriously.
I can understand how someone else may feel differently because they may not have the same control of their career or business. When I first went into business I needed other people more than they needed me and my philosophy was very different than it is now. Today, after a quarter century in business I have enough business coming to me to afford me the luxury of being selective in who I take on as a client and setting my terms of how I work.
