fear

There are two basic motivating forces: fear and love. When we are afraid, we pull back from life. When we are in love, we open to all that life has to offer with passion, excitement, and acceptance. We need to learn to love ourselves first, in all our glory and our imperfections. If we cannot love ourselves, we cannot fully open to our ability to love others or our potential to create. Evolution and all hopes for a better world rest in the fearlessness and open-hearted vision of people who embrace life
— John Lennon

You don’t have to run a big business, fly a balloon, or break records in a boat to learn from and use the lessons I learned. Your goal can be small. Student magazine was very small at first. I sold space in it from a payphone at school because I believed I could and would do it. If something is what you really want to do, just do it. Whatever your goal is you will never succeed unless you let go of your fears and fly.

Since the beginning of time, man has largely been controlled by emotions, fear and greed. When a student of market action allows these emotions to influence his market response, he loses many opportunities in the market. The student must at all times resist these two emotions. Confidence and courage are required to overcome fear and greed. Courage is inborn. Confidence is gained by study, study and more study
