*No matter how shiny something is in the moment, everything degrades over time, which leading with this assumption means, what makes us happy right now, is going to face "happiness degradation" as we go forward.* — in other words no condition is certain to be permanent. The earlier one recognizes and acknowledge this fact the better. 

In my opinion, I feel living in the moment and living for a futuristic purpose are sort of interwoven . Living in the moment is unavoidably living in the present , what happens in the present sort of forms a foundation for what is coming next in the future. A balance just needs to be struck on what defines our attitude to living in the present and what we envisage for the future.
