“We often add to our pain and suffering by being overly sensitive, over-reacting to minor things, and sometimes taking things too personally.” by Dalai Lama
So profound teaching!!!
Some of us, we love to over reacting and super sensitive about minor things, this is one the root of suffering to block our happiness and also peace of mind.
Learn to let go and understand ” impermanent of life”, things are keep changing and nothing remain the same. A person can’t be the same person, their mind are keep changing constantly. Even a thing (Object), can’t be the same even though physically it look the same.

Always remind yourself “This too shall pass”. Don’t take things too personal and over sensitive.
You are holding the key of happiness.
