What is a lifestyle and how is that different from a life? A lifestyle is about brand names and buying identity or fame. Lifestyle gives a false sense of peace and acceptability that comes from others recognizing what you’ve bought into (as well as bought). If your car, clothes, and home are expensive, you’re sophisticated(世故的) and stylish. If you have the right kind of job or go to the right social gatherings, then you receive the insincere approval of others. This means that your self-esteem(自尊) is always at the mercy of others, with no appreciation of you as an individual.

A life, on the other hand, is very different. A life is what you lead when you know what matters most to you. It is very simple and comes from being connected to what you know is important and being willing to put that first, no matter what others may think. When you create a life vs. a lifestyle, your self-esteem comes from what’s inside you, not what others think about you.

Lifestyle is expensive financially and personally, because it costs a great deal to keep up appearances and do what you think is socially acceptable. A life is not expensive. Rather than using personal or financial resources, a life generates energy and staying power. It’s about liberating yourself from the mindless consumption that society expects. It is about making the choices that are in line with your values, instead of using up your bank account or energy for no heart-driven reason.

How can you make the change? Understand the difference between a life and a lifestyle. Analyze your current lifestyle to see what is costing you in money, time, stress, and energy to maintain it. Let go and make room for what is really important to you, what supports you and brings you joy. Remember who you are from within, not what you own!
