Are you being humble regarding your criteria for "happiness" or are you made to eat the humble pie?
There's a difference in what you think and what actually works for you, habits have to be cultivated, criteria has to be tweaked to individual needs.
If the norm doesnt work for you, dont be the norm then.
If changing the surroundings and people around you doesnt work, its the mind that needs to be refocused.
IF that cant work, then your mind is not focus on the norm.
Adapting and forcing your mind to adapt is different.
Be Honest about what is "happiness" to you.

and some phrases from my book today

"Our thoughts make us what we are"

"You are not what you think you are, what you think, you are"

"The mind is its own place, and in itself

Can make a Heaven out of Hell, Hell out of Heaven"
