This is different for every single human being on this planet. And it is something that can change for each person on a very fluid basis.
So what matters most to you? If you answer honestly, you will find the meaning of your life to you.
I find the list is not short, and it is difficult to prioritise. So in no particular order my top five:
My husband , our life, our health, trying to be kind, living a good and honest life.
This is now, ten years ago it was probably different, in ten years time it may have changed again. Life is full of uncertainty, so I will keep wishing on shooting stars and four leaf clovers, and be grateful for all I have.
Incidentally if your list starts with money, power, or world domination, It might be time for a serious rethink of your priorities!
And if you want things really putting into perspective, my dear friends son, who is 28 years old and spent his childhood overcoming birth defects, became a teacher, now has been diagnosed with stage 4 Cancer.
Be grateful for everything in your life, every single day.
