Over the years I've cut off a number of people from my life for one reason or the other. I happen to be a very tolerant person who would rather keep the peace than have a confrontation. What I do is avoid situations that can lead to confrontations. Life however, isn't black and white. You can avoid fights and confrontations all you want, be the nicest person ever and trouble still finds it way to your door.
Everybody's got a limit and when I do reach my limit, I cut people off. My limit varies with each case, it could be really elastic and also be really short. I don't make the rules. People have tagged me a no-nonsense person and there are also others who think I can be pushed around. The former are those who have a close relationship with me and have seen me cut people off before.
I value my peace of mind so much and when it's disturbed too much, I remove myself from the situation. People make it seem like cutting people off is a bad trait, well, not really. Some things don't need to be resolved and stressed over when you can just 'mute conversation' or 'block' like they do on twitter.
You need to realise you're not going to be in everybody's good books, don't even try to be. I'm very okay knowing I have a few people who don't like me or my choices. The good thing is my life goes on and I'm totally unbothered. Infact you know you made the right decision when you do not have a care in the world after cutting them off.
So I encourage you today, do some introspection and access what you should or should not continue to tolerate. Does it give you peace, do they drain you or fill you up? Know when to resolve and when to cut people off for your sanity if you must.
