Buy less, do more. We are impoverishing ourselves, individually and as a nation, buying things we don't need and don't actually want. If you have closets, garages, and storage lockers full of stuff you're not using, you don't need any more stuff!
Educate yourself continually. Ignorance makes you vulnerable. It is easy for people to take advantage of you, rip you off, and abuse your rights when you're not informed. Choosing to be ignorant means saying "Here, other people in the world! Why don't you run my life for me?"
Depend as little as possible on others. No man is an island, and it's impossible to do everything in this world entirely on your own. However, you should be very mindful of what you're choosing to have other people do for you. You may be better off doing it for yourself.
Make purchases mindfully. An aware consumer makes better choices than a consumer who is functioning on auto-pilot. Think about what you buy, where you're buying it, and why you're buying it. Make sure your purchases are in alignment with your belief systems. Think about what things cost to produce and market: if you're paying an exceptionally low price for something, you can be sure that someone else is paying dearly, generally in terms of their labor/quality of life.
Make creativity central to your life. We were given imaginations for a reason. Creativity is as vital to our well being as physical exercise. It doesn't matter if you never 'learned' how to be creative: something as a simple doodle can be the gateway to an innovative solution to a tough problem. Humanity survived & thrives because it is innovative and has the ability to transcend history, seeing beyond what has always been done. This power is inside each of us: don't think it belongs to ivory-tower academics and government think tanks. But you have to use it, or you will lose it.
