You do have all the things you need. It seems now you are seeking the tools to fully realize that reality.
Have you tried mindfulness meditation or Buddhist teachings?
I recently posted this in another gear forum, but it also works here:
As a species, we have evolved to seek dopamine, and ignore contentment.
Other animals have also been built, through natural selection, to remain dissatisfied and always seek rewards.
The “next thing” intrigues us, we imagine the possibile experiences with that thing, and the anticipation of obtaining it primes the reward center.
We imagine it as one of many keys to happiness. But happiness is fleeting (again, thanks to evolution), and so once the thing is obtained, our desire for happiness (which disregards contentment) seeks the next thing to be fascinated by to re-up on dopamine.
Mindfulness meditation helps you notice these feelings and learn to sit with them, and let them come, and ultimately pass through.
