It is quite a paradoxical question. If you have to tolerate for the rest of your life, then what is your definition of 幸福? Do you only need to put up with someone sometime in exchange for it?
Obviously it doesn't mean happiness because one cannot be happy if you have to constantly put up with someone. If it means money then to me it is not worthwhile to do so. If you have to put up with someone's habit, behaviour and etc then it depends on what it is and how much you love him/her.
For the question, it is very vague. My answer is that if one needs to tolerate someone then maybe it is not worthwhile. If it is love then love shall never have to put with up someone.
Miss,
I think 一世幸福 = both understand each other strength and weakness,
understand both value systems ... etc ...
If you are in doubt on a relationship, there MUST BE A REASON !!!
It is not fully sacrifice will work or patience will work ?
"Dynasties can change, but a person's character hard to change" - chinese saying ...
so you must like that person's personality ... and can deal with him completely before you can get 一世幸福 !
一世幸福 IS NOT marriage to the guy YOU LIKE ....
it must be mutual ....
that is why in the west, we see so many happy couples never marry and live together happily for so many years ... and get married when they are 60 or even 70 ... because they know what is 一世幸福 ...
一世幸福 should not have pressure, no doubt ... people stay together because they like to be with each other .... for sex ... for money ... for look ... for companion ... for doing sport together ... who cares ... but they are together for a reason ...
once you understand this, then you know what is 一世幸福 ...
marriage and all kinds of stupid consequences ... are just not natural ...
It is just a SHOW for everyone around us ... or for the bride to be shining on that day ....
that was it ... 一世幸福 must maintain by both persons ... live the life together rich or poor ... full understanding and fully balanced love ...
旁邊ge人, I can always tell you, if HE love you more , you are most lucky ...
never love a person MORE than he love you ... it will be painful ... or not smooth at the end...
good luck ...
