I guess you could say everything is in your control but, I do believe there are a lot of things that aren't. So do you find yourself saying "sorry" for those things, and have you tried to stop?
I know I have a problem with that, and not sure how to stop
Firstly, you have to stop that because if one is a repetitive apologizer they are deemed as disingenuous.-In other words, you are never truly sorry if it is a major faux pas that requires a believable apology..."I'm sorry for your loss" means Nothing coming from an over-apologizing individual.
Often, simple courtesy can eliminate the need for apology so you may want to start there. One does not have to "I'm sorry for being late on our call" IF one DMs about an hour before notifying Business Mate that you are running 15 minutes late. NO apology necessary and straight to Business with every intention of ending the Call on time... And the same is applicable for one party forgotten on group emails... just forward the damn thing-they'll figure it out and believe you me know you are not perfect !!!
Do not be an over indulgent, self-protective, insecure, and HEARTLESS over-apologizing individual who simply want s to hear their voice echoing... Your confidence will rise as you desist in degrading yourself and others will enjoy a more positive force in their life. And, they will believe that you actually have a conscience and know how to feel and when to express it with a HEARTFILLED understanding. :-) Good luck with it.
