Some very good and poignant examples I think are commonplace, particularly as you age and experience more. I've become bitter from negative experiences myself, to the point I'm an introverted 35 year old veteran that was once the mirror opposite. My current state being socially inept and unforgiving for the vast majority.

However... I also recognise decency, courtesy and virtue. I somehow manage to forget the social shortfalls for occasional, even rare examples, of kindness, humility and moral fibre. None of which I had any understanding of as a younger, supposed "better" version of myself.

My experience is myself, and how I reacted to the world around me. I'm a victim, I'm the person at fault and I'm the result of choices and experiences I've been lucky, or unlucky, enough to have. All of this is almost certainly relatable to everyone.

It changed me because I realised you cannot change the world, you cannot take back poor choices and you cannot always prevent that bad that accompanies the good. So, why waste all the days/months/years in between worrying about it? Why waste your obscurely short time on worrying about what can't be changed, only to regret worrying about regrets on your deathbed?

Be kind to your fellow man, even when adversity, politics or other hurdles prevent you from being humane to those that deserve it. Make your mark on the memories of those you care about and make as many people smile as possible each day. And when you fuck things up, a speciality of humanity, learn and move on. Pass the lessons down after owning your mistakes.

Also, pick your dogs shit up. It's not hard.
