Your perception really determines whether you succeed or fail in life. If you grow up believing that the world owes you a favor, your dad/mom failed at his/her career because of an unfair boss, or jealous co worker, then you too will find the reason for your personal failures lies within somebody else, some hidden external force that is working against you.
The only hidden force working against you lies within your very head, your subconscious filtration system also known as your paradigm. Your own paradigm determines how you view the world. Babe Ruth looked at every failed swing as an opportunity to succeed at the next swing. A person with a flawed low self esteem would have quit after the first failed 100 swings at the ball. Ponder this - do you fail simply because you give up before you can a master the activity?
Perhaps you measure your success rate against a co worker who has early success and you have a late success rate. Sprinters who measure their endurance against marathon runners will always come up short,as will marathon runners who attempt to compete against sprinters. Each race has a unique style and definite set of skills required. As a society we often focus on the over night success rather than the marathon runners , but both win their races.
