Human psychology has evolved to be motivated through moderately strong, short term desires, like hunger, sexual arousal, being cold, being tired, etc ... and to constantly fulfill these desires throughout the day. In their natural condition, humans are strung along by their biology, for example in relationships, where they first have sexual desire, which they fulfill; then they might fall in love and have a lot of sex, a period which might last roughly six months to a year, and then, in pre-contraceptive times, a baby usually appeared and you had another clear purpose to fulfill, raising a child, which gives you many small desire-fulfillment loops throughout the day.
If you were ever backpacking in the mountains, you know how intensely satisfying everything becomes, from half a banana to shitty instant coffee, to 20 minutes of rest in the sun or a good night's sleep in a sleeping bag. The pleasures are enhanced from two sides – they are more pleasurable because you are more deprived (are hungrier, more tired, colder etc ) AND they become more precious/ you savour them more, because you have a limited amount of them.
A Somalian immigrant can't understand that. He has probably lived a more satisfying life on a wheat farm than we westerners ever will.
