Knowledge, in truth, is the great sun in the firmament. Life and power are scattered with all its beams.

Understanding does not sit in one place; it radiates into everything you do. Learn how money works and your job changes, how bodies work and your habits change, how arguments work and your friendships change. That spread is what separates knowledge from most investments, since you cannot confine it to the department you bought it for. Power follows it around almost as a side effect.

Choose one subject this season that you have avoided because it felt technical or foreign. Give it a month of real attention rather than a weekend of skimming. Then watch how many unrelated decisions become easier.
