I ask why does it matter? The issue of happiness guides our primal mind. Basically, you can stop thinking and be happy or you can struggle and be unhappy. Why can't we struggle and be happy? This seems to be a point of contention. People believe that struggling and suffering makes us unhappy, but it makes us happy as long as we have a dream. (The goal to struggle toward.) Now, we have thrown back to Aristotle. Just stop worrying about the perfection (Plato) and just be. Do not worry about the rounding, judge (for yourself) as a whole whether your life is better or worse than it should be. This will be the best thing in the end. Buy some real estate because that is fixed. Find a place in your mind to know that you have improved.
