"Not to move forward, to stay where we are, to regress, in other words to rely on what we have, is very tempting, for what we have, we know; we can hold onto it, feel secure in it. We fear, and consequently avoid, taking a step into the unknown, the uncertain; for, indeed, while the step may not appear risky to us after we have taken it, before we take that step the new aspects beyond it appear very risky, and hence frightening. Only the old, the tried, is safe; or so it seems. Every new step contains the danger of failure, and this is one of the reasons people are so afraid of freedom."
