To make good use of your time in this world, think of your life above all as a quest, a seeking, a searching, a striving. For what? For the ultimate in reality, truth, value, and for their existential appropriation.
One appropriates reality by being authentic, truth by being truthful, values and norms by living them.
It may all be absurd in the end, a "tale told by an idiot, full of sound and fury, signifying nothing." But one cannot live well on the assumption that it is.
So assume that it is not and explore the question along all avenues of advance.
