Want something to last longer? Find the meaning behind it rather then the fun in it.
We as humans have an odd relationship to the memory of feelings.
We usually forget how fun something was. This is why we chase high after high and thrill after thrill.
We also forget how painful something was. This is why some people have more than one child.
But we rarely forget how much something meant. Significance seems to stick around.
Deep community promises more meaning than fun (and than pain). Impact beats excitement.
