The satisfaction that comes from the outside world is transient. At death it will all be lost.
Human life is given to you for the sole purpose of realizing the Self. If you die without realizing the Self, your life has been wasted.
Death can come at any time. If you are constantly aware of the possibility that you may die at any moment, your enthusiasm will increase. Try to cultivate this awareness and see if it makes any difference to your sadhana.
