Letting go of resistance is fully dependent on awareness
Awareness that if you are able to let go of the expectation to hold on to every pleasure, then the fear of unpleasant events will also begin to dissipate
It is entirely an awareness
Once you are aware of this resistance, it’s much easier to live life with a clearer headspace
How do we get to this awareness?
Well that has to do with your patience
And we are all impatient, unfortunately
All I can say is good luck with that. Perhaps try meditation. Or yoga.
