good thoughts, but it is not postponing happiness. that is predicated on the assumption that there is substance to the wt promises. But, all of them have failed: paradise "soon" 1914, 25, 75, 2075-- so why would you believe the other promises, the resurrection, to immortality or eternal life would be any surer? when the easy ones failed?
Living for the future is not postponing happiness, it is cancelling it.
