You are not barred from attaining greatness by heredity. No matter who or what your ancestors may have been or how unlearned or lowly their station, the upward way is open for you. There is no such thing as inheriting a fixed mental position; no matter how small the mental capital we receive from our parents, it may be increased; no man is incapable of growth.
Wallace D. WattlesThe scientific use of thought consists in forming a clear and distinct mental image of what you want; in holding fast to the purpose to get what you want; and in realizing with grateful faith that you do get what you want.
