That is living.
Life is nothing but a succession of actions.
This is easily proven. For every action you do, there is also an action that follows.
Except for one action.
Death. That is the final act and nothing follows it. No action at all.
Thus, to take action is to live. To live is to take action.
Ask yourself, "what will you do next?"
I shall do the same. First I ask, "what I do now?" The answer is, I sit here, on this IKEA bought chair, keeping my legs on the other chair, wooden one, listening to Eurythmics on YouTube.
What will I do next? Probably sit here for some more, listen to some more songs, maybe watch an episode of some old obscure British comedy series and then go to bed.
Why do I do that? Why is that the likeliest action to follow? Is it the optimal, or even best, thing to do?
I don't really know the answer to those questions.
But if I don't know, really, why I do what I do, why do I do them? Does it make me happy? Satisfied? Will it make my life better?
I don't know the answer to any of these.
Thus I have to conclude that what I do is not in my control, not really. The reasons for me doing them are unknown to me. I do things, when asked why, I don't know the reasons to.
Many would probably say that they do so and so because they like doing so and so. What is this liking?
Is it the path of least resistance? In many cases not, for many climb mountains and and jump out of planes and travel to far away places and say they do it because they like it, but these things require much energy and resources.
Thus, the question becomes not what will you do next, but why will you do it? For you will do something.
To some this question is meaningless. To some it is not.
It is often said that you should do what you feel is "right" or "what you want to do" or "what makes you happy".
I am hardly an expert on life. And I have just proven I don't know myself enough to even tell why I do the things I do.
Ergo
