So I always imagine it a bit like this.
Imagine you are playing the SIMS, lo and behold you are your own SIM. But the objective in the corner doesn't specify money, it specifies well-being and happiness.
Your SIM is only programmed to take care of their base necessities, but those will only get your well-being and happiness bars up about 20%.
What do you do to fill them up the rest of the way? Mind you, some ways to fill the bars will be counterintuitive, like exercise, or learning a new skill. Though it needn't be those specifically.
And to make it harder, there is a diminishing return even on things that work, so you have to be sure to add variety, just a little, to keep the bars going up.
The most important thing, is you need to genuinely want what's best for yourself. Not what's most comfortable, but what's best. There is no answer anyone can give you to what that best something is, you have to answer that for yourself.
And if all of this seems like stupid bullshit to you, well this is just my own opinion, to which I make no claim has it's origin in the mind of greatness.
