Stress in my life and managing it...advice please?

I seem to be very bad at managing stress in my life both in the workplace and with people and situations that get on my nerves. I have a heavy profession and have sometimes left jobs due to burn-out or at times take things too sensitively. Now I'm finally (in my mid 40s ) doing something about it by starting stress management classes. These are one to one and will hopefully turn my bad habit around. Sometimes, some friends get on my nerves, one in particular when she criticises things I do in my life. I don't want to fall out with her but I really thing that she does not have the right to criticise my lifestyle. I live a good decent life, am not a criminal, earn my own living and have no addictions. She gets specifically annoyed that I travel a lot (I like it and work hard to afford it) and I often date guys who are lots younger (I look 10-15 yrs younger). How do I deal with this criticism from some people and in the workplace?

Remember where to put the ownership of the criticism. If THEY have a problem with you or something you do and YOU don't, then they own the problem. Do nothing.

If you hold ownership of the problem, then try to figure out a way not to continue the thing that is bothering them and thank them for the advice.
