(Tom says this is a plumber's view of philosophy.)
We ask, What is my inspiration? We say (don't deny it), Ooohh, but I'm not inspired, I don't know what I want, I have no IdEEEEEEEEAAAAAAAA. But that is just one end of the pipe and the pipe has another end and that, over There, is the other end. The questions There are quite different: What do I feel like, having gone through that pipe and ending up afterward, here at the other end? Does it feel good, or bad? Am I happy, proud, am I at least satisfied, or am I ashamed, sad, guilty? Do I feel good or bad about myself, do I like what I became, now that I went through that particular path, that I chose it and went through it and ended up here.
Thinking about it backwards, from the other end, you might consider what your aspiration was, rather than what your inspiration might be. What kind of person are you glad, or not glad, that you became, with the choices you made.
So, what's the answer for you? What path, direction, vector, pipe will you enter upon, today, this life, and how do you think you're going to feel about it afterwards?
This is a slightly different way of thinking about what we might want to do.
You could really aim high if you could think backwards.
