This quote by Eckhart Tolle is a good one. I am not sure if it is from the book, “The Power of Now” or not but it is a quote that makes you think twice and re-read it.
When reading this quote I first thought what if what I accepted is about the negative in life then I realized that fully accepting something even if it is negative puts a lot of pressure aside and it feels like a weight has been lifted off of your shoulders. You no longer have thoughts like, “How could she/he do this to me!” and “Now what am I going to do!”. Instead, your mind will accept it and you will find that your mind will switch a flip and start thinking of ways to solve it instead of coming up with ways to make yourself feel even more awful. While deep in a meditiation I was told that the two most important words were acceptance and understanding. They may not be the best words for you but I have found to help with my own self issues and to better myself, they are the best words for me.
I would recommend sitting down and meditating and let your mind go blank and notice where your mind wanders too. Is it a good place or a bad place? Notice that, accept it, understand it, then let it go and go back to leaving your mind blank. When your mind wanders again repeat the procedure and try to go a little longer the next time before your mind wanders. Eventually, with practice, you will be able to sit still long and quiet enough that the universe/God will speak to you and give you what words are the best for you.
