I don't think I have made peace with any of my long list yet. Although I feel like I am getting to an age where I need to (early thirties). Is this an age thing? How do you make peace with things that cause you so much pain? If the big things don't matter then what really matters and what are we even doing here?
All that goes over in my head is the Linkin Park song lyrics from 'in the end', "it doesn't even matter how hard your try".
The serenity prayer is a cliche but if you look past the cliche, it's incredibly valuable advice:
God grant me the serenity to accept the things I cannot change, courage to change the things I can, and wisdom to know the difference.
Whether or not you believe in God it's good advice. The ability to make peace with what you can't change (your parents, your height etc), be brave enough to change what you need and want to change (your job, weight, partner, home, financial status) and being wise enough to know the difference between the two is the recipe for happiness.
Big things matter a lot but you have to ask yourself at some point - what is the value in being miserably obsessed with things I can do nothing about. Having indifferent parents or a chunky build or rubbish singing voice or a son with SEN and fragile physical health - I can't change these, so I have stopped getting angry about them and become more forgiving to myself and life in general that this is what life dealt me - no one's life is perfect. These are my burdens. The best way to carry them is lightly with total acceptance.
But being overweight, broke, friendless, depressed - I can and have changed all those for the better and have a lost of similar issues to deal with that are empowering when you improve them.
