I've learned that people come and go in our lives. Even if they have promised a thousand times that they won’t. It's not the end. Just the beginning of something new. Took me a bit to come to terms with this, but I got it!!
There are certain things in life where you know it’s a mistake but you don’t really know it’s a mistake because the only way to know that it really is a mistake is to make that mistake and go, “Yup, that was a mistake”. So really, the bigger mistake would be to not make the mistake because then you’ll go about your whole life not knowing whether it was a mistake or not.
All things are perfect exactly as they are ~Buddha
