I have learnt so much from this post. Am so grateful to @gavvet, for these wonderful lessons you have brought my way these past days.
As my own humble contribution, I believe we should make it a habit to tell people thank you. To express your appreciation, sincerely and without the expectation of anything in return. Truly appreciate those around you, and you'll soon find many others around you. Truly appreciate life, and you'll find that you have more of it.
The important questions we should ask ourselves daily is Did I offer peace today? Did I bring a smile to someone's face? Did I say words of healing? Did I let go of my anger and resentment? Did I forgive? Did I love? These are the real questions. I must trust that the little bit of love that I sow now will bear many fruits, here in this world and the life to come.
Also,Happiness is a choice. You can choose to be happy. There's going to be stress in life, but it's your choice whether you let it affect you or not.
As a final word, If the only prayer you ever say in your entire life is thank you, it will be enough.thank you.
