Your Life Is an Expression of Your Mind
The result of our actions is determined by what we conceive in our minds. If we have a strong desire to succeed and visualize this success in our minds, then we achieve it. On the other hand, if we think, "Maybe we can't," or "Maybe we will fail," then we are likely to fail.
I believe nothing comes to us that our mind has not summoned. Thus, the reality that surrounds us is a reflection of our own minds.
