If happiness can be measured, let's call this unit of measurement "Happiness Index".
Assuming you donate a piece of bread to a starving begger, his happiness index, let say is 8 out of 10.
Now, assuming you give your rich friend a diamond ring, his happiness index is probably the same, 8 out of 10.
Are they both equally happy? Yes. The Happiness Index is the same, 80%.
But both mediums to happiness, the bread and diamond ring, are measured differently in monetary terms.
Everyone of us have our own lives to lead. We definitely have our own mediums to happiness at different points of time and place.
What influence our happiness index then? Our past experiences. Then comes how we view life and future expectations. With these, an "Auto" happiness index will arise. That is where most people will stop at bad times. We indulge ourselves in the low or negative "Auto" happiness index. Our experience may not have trained or prepared us to switch the "Auto" to "Manual". "Manual" Happiness Index can be cultivated. It only takes minimal effort to kick off the chain of events. A change of mind is all that is needed. It is not impossible. It is as easy as a snap. A change of mind is the easiest thing to do in life.
Yes. A change of mind is the easiest thing to do. Effortlessly.
