It's not easy dealing with insults, especially during times I hate myself. I have a few different tools I'll share. I'm far from perfect and don't use them as often as I should, but when I do I find it helpful (most of the time)
Up first, the questions for myself.
1. Is it true?
If its not true, who cares, it tells me more about the person who said the words. If it is true, I move on to the second question.
2. Does it matter?
If it doesn't matter, than who cares. Once again, this tells me more about the person who made the comment. They are focused on insignificant matters that aren't worth my time. If it does matter, I move on to the third question.
3. Is there anything I can do about it?
If there is nothing I can do to change it, there is no point getting upset about it. Should I cry because I'll never be over 7 feet tall?
Then come the quotes.
“If anyone tells you that a certain person speaks ill of you, do not make excuses about what is said of you but answer, ‘He was ignorant of my other faults, else he would have not mentioned these alone.'” –
Epictetus
If I'm in a f*** the world mood, the quote by Epictetus is fantastic. I can just laugh and say "if you only knew"
“Choose not to be harmed — and you won’t feel harmed. Don’t feel harmed — and you haven’t been.” –
Marcus Aurelius
This idea from Aurelius is much harder to put into action. I try to remember it when getting cut off in traffic, if nothing bad actually happened, then nothing bad happened.
As far as I can tell the only insult that should have an impact is the one based on a truth that matters and I have some control over it. That doesn't mean it should upset me, just open my eyes to an area that could use some work.
We have a lot of stuff to work on, other than the things the people around us know about. The kind of work we have to put in to make progress isn't easy. We aren't capable of fixing everything we don't like about ourselves at once. So never forget where it is on YOUR list, if it's not a top concern for you and your T at this time, even if it's true and matters there are much more important items to be focused on.
Hope you foud something helpful in here.
