Wow! Awesome article and Awesome advice. Have I said it's awesome??! LOL
Of your four advisements, I like #3 & 4. Communication is vital. Every day we should respectfully talk about the things that bother us, with the people we love. Otherwise, as you said, you hold grudges and fester negativity.
As for #4, that is very responsible of you to refer people to seek help. Sometimes people need help, and we can't advise them, other than to refer them to professionals. Job well done!!
One suggestion, I noticed you hyperlink some credible articles in your story. You may consider just listing your sources at the bottom in a "reference" section. I have found it gives your advice significantly more credibility.
Overall, awesome article with awesome advice!! Thank you for sharing!
