Yes, it's good to know how to optimize, but don't feel obliged to. Just because you can do something doesn't mean you must. Do what you want. Also, "Premature Optimization is the Root of all Evil" -- Donald Knuth
Life is so immensely broad, and we can do whatever we want. We have a giant sandbox at our disposal, and whatever we want to do is fine. Because we can. Simple as that.
That's why indecision can hinder your progress so much. You try to make the "correct" choice, but more often than not there is no real "correct choice". Your choice is the correct choice, and all the energy spent worrying and hesitating is wasted. It's all natural, of course. Everything is natural. But it makes one wonder what one can accomplish if one were to trust oneself fully, unconditionally, genuinely, regretlessly, and joyfully.
Sounds. They're everywhere. At least everywhere I've been.
Attempt to map sounds to numbers bijectively. Given a finite sampling rate, it's possible, right? So I wonder... how to map it? The individual, "purer" sounds would be integers. Countable, even if infinite. Clinks, steps, single instrument notes. Those sound like integers to me. Then music pieces... sequences of integers... often cut into parts, mixed and matched, harmonized together... likened to rationals? Maybe? But sounds in nature never stop. They go on forever. The wind through a tree's branches, a river stream. Like... irrationals. Pi and e should be out there somewhere. Just a conceptual whim.
