Self-acceptance begins in ...

Self-acceptance begins in infancy, with the influence of your parents and siblings and other important people. Your own level of self-acceptance is determined largely by how well you feel you are accepted by the important people in your life. Your attitude toward yourself is determined largely by the attitudes that you think other people have toward you. When you believe that other people think highly of you, your level of self-acceptance and self-esteem goes straight up. The best way to build a healthy personality involves understanding yourself and your feelings.

Quotes from the same author

Your success in life and work will be determined by the kinds of habits that you develop over time. The habit of setting priorities, overcoming procrastination, and getting on with your most important task is a mental and physical skill. As such, this habit is learnable through practice and repetition, over and over again, until it locks into your subsconscious mind and becomes a permanent part of your behaviour.
There is never enough time to do everything, but there is always enough time to do the most important thing.
Goals are the fuel in the furnace of achievement.
Whatever we expect with confidence becomes our own self-fulfilling prophecy.
You can only grow if you're willing to feel awkward and uncomfortable when you try something new.
