The cited text is primarily wordplay, rather than clear communication of an idea. But my guess is the writer was just trying to find a "clever" way of saying what many others have expressed as...
Live for the present, not the future (that's a lot of written instances in Google Books)
...the meaning of which I hope I don't need to explain.
Some people may think OP's cited example is "well phrased" (or at least, "clever"), but I don't like it much, because the verb form to design inherently implies making a plan for the future. So the only way to make sense of designing for the present as somehow being the "opposite" of postponing one's (future) happiness is to suppose it means make plans to achieve happiness as soon as possible in the future.
Strictly speaking I doubt design is really a suitable verb for what the writer is trying to say. It's true that he might be advising us to design / plan our lives with the intention of being happy in the very near future (which is almost the same as "the present").
But most likely he's advising us to find / take pleasure / happiness in our current circumstances. Sometimes that's just a matter of having an optimistic attitude (look on the bright side; see your glass as "half full" rather than "half empty"). Other times it's a matter of making particular choices (indulge yourself and spend your money now, rather than saving it and waiting until you're too old and decrepit to enjoy it).
