The Comfort zone, the learned helplessness, The path of least resistance
3 things (enemy) exist to hold people back from success.
1) The Comfort zone: People do things in the way they feel comfortable; they don't like to change - 80% of people find reasons not to change, even the change can be positive or beneficial.
2) The learned helplessness: This is where people feel I can't do it.
3) The path of least resistance: People look for an easy way to achieve a result. But, nothing worthwhile can be achieved easily. Everything worthwhile requires a long-period of HARD WORK. With many failures along the way.
