None of your attachments are real
You don’t need them
It’s not wrong to be attached to things, to like to have your life a certain way - your home, your job, your relationships - but it will hinder you if you don’t keep in mind that all things are bound to change.
It serves us better to remain cognisant of this propensity, or pull, even, of everything towards change; everything that’s certain now is unravelling into a different future. There is no way around that, so the more you can allow change to be a positive thing - learn to trust your own skills and responses, embrace the unknown and the unexpected, look ahead to expressing yourself and living out your essence in new ways - the easier and smoother life will be for you.
There are a multitude of ways to do this but here are a couple:
Update how you think about pain and failure. Everything in life is an opportunity for pleasure or an opportunity for learning; occasionally things are both (yay!) but it’s not possible for something to be neither. The things we see as negative are always lessons, opportunities to learn; start calling them that and stop calling them disappointments, misfortunes, losses, pain, shame, failure.
Be deliberately grateful for each random or unexpected occurrence in your life, before you see it as “good” or “bad” express gratitude: for its uniqueness, for the diversion to a better path, for the information it provides, for what it has to teach you. This will feel like utter nonsense to start with (saying thank you when **** happens) but stick with it: eventually it comes naturally and it will change your life forever.
