How do I judge whether a pay package is right for me?

You can read a full compensation package clearly and know what it is truly worth to you. That is a quiet form of power. Most people sign things they do not understand. You do not, and that keeps you from being led by a big number that hides a small reality. Seeing clearly here is not just about money. It is about knowing your own worth and what you actually need, so you can weigh an offer against your life rather than against someone else's excitement. Clarity like that is hard to pressure and hard to fool. Use it to help someone facing an offer they cannot read. Walking another person through it sharpens your own eye and passes on something genuinely valuable.
