I used to when I was at school but that is just it.. they are childish and immature, more than that they are a waste of energy. I can't be bothered to use up valuable time being negative and focused on crappy behaviour by another person when I could spend it being happy and thinking nice thoughts (how hippy of me hey?!)
I come across some very average attitudes in business (personal too of old but not so much these days as I have a pretty gorgeous tribe). There are often those you go out of your way to help only to get no thanks, a complaint despite the effort or worst of all have them completely disregard your time and do something that shows they didn't even value the relationship you had created with them.
It used to leave me grumpy and sad for quite a while, it used to have me never wanting to help others for fear of a repeat and sometimes I even wanted to scream and shout but I didn't and I don't
Their attitude is the crap one and they are the ones loosing out. I go right along and ignore it these days knowing I did everything I could and can sleep at night knowing I tried.
I don't bear a grudge.. I just know that person is well and truly due absolutely no good karma from me and that I will move on and spread my love elsewhere.
I am a girl with a lotta love and I get lots of chances to spread it far and wide in business so more fool them I say. Life is too short to allow crapness to consume it. Onwards and Upwards I say :)
Do you bear grudges? Some of my mates do as they say they just cant see past it.. I get it, I do. I just don't do it anymore.
