In search of happiness

Are we so obsessed with being happy in the future that we completely ignore what makes us happy today? I have always lived by sacrificing the present in order to build a happier and more secure future and I think it is starting to take its toll. Years have gone by and it does not like I am getting any closer to achieving my goals... At what point do you decide to stop chasing future happiness and seize the day? Or maybe I am just fooling myself... Maybe some people are not capable of being happy... I must be missing the happy gene and maybe I should just accept that and lower my expectations.
