I think the existence of good and bad feelings (e.g. happiness and suffering), and the hope of having good feelings in the future, is indeed the only basis for finding and recognizing meaning in life.

And I think, due to evolution, that humans have a particular relationship to suffering, such that we are liable to fall into a depression or malaise if we don't have a certain amount of stress that motivates us to do things that make us happy.

But from a more philosophical perspective, I do think that the only logical goal in life is to look to find ways to experience less suffering, and more happiness overall.

The capacity for us to experience feelings on the spectrum of extreme suffering to supreme happiness is what gives life meaning. But I don't think the actualized experience of suffering should be celebrated. The extent to which humans need to have felt suffering in order to appreciate happiness is really just a quirk or failing of the human body. And I don't think it implies a universal truth that sentient beings should actually welcome more suffering.
