For what purpose humanity is there should not even concern us: why you are here, that you should ask yourself: and if you have no ready answer, then set for yourself goals, high and noble goals, and perish in pursuit of them!
Thus the will to power strives towards oppositions, towards displeasure. There is a will to suffering at the foundation of all organic life (contrary to "happiness" as "goal").
Try to relax, and you will find out that you feel more tense than ever. Try harder and you will feel more tense and more tense. Relaxation is not a consequence, is not a result of some activity; it is the glow of understanding. This is the first thing I would like to relate to you: life is purposeless. It is very hard to accept it. And why is it so hard to accept that life is purposeless? It is hard because without purpose the ego cannot exist. It is hard to conceive that life has no goal because without any goal being there, there is no point in having a mind, in having an ego.
Life seems to be a process of replacing one anxiety with another and substituting one desire for another--which is not to say that we should never strive to overcome any of our anxieties or fulfil any of our desires, but rather to suggest that we should perhaps build into our strivings an awareness of the way our goals promise us a respite and a resolution that they cannot, by definition, deliver.
To remain indifferent to the challenges we face is indefensible. If the goal is noble, whether or not it is realized within our lifetime is largely irrelevant. What we must do therefore is to strive and persevere and never give up.
If life's journey be endless where is its goal? The answer is, it is everywhere. We are in a palace which has no end, but which we have reached. By exploring it and extending our relationship with it we are ever making it more and more our own.
