For me, learning to say "NO" was both the hardest and best thing I've ever done for myself. Pleasing others and then hating yourself is spiritually and emotionally destructive. When you learn to say "NO", all the other items on this list will fall into place . Trust me on this.
My Mom was cleaning out her basement and came across some things that belonged to my Grandmother. This was one of those things. She knew I was having a rough day(s)... so she texted it to me. It took 6 texts to type it all... And at the end, she said, "Hope it made you smile. Sounds like something she would say!"
