To give oneself is the only way of becoming oneself.

Every great accomplishment of mankind has been preceded by an extended period, often over many years, of concentrated effort.

One hour per day of study in your chosen field is all it takes. One hour per day of study will put you at the top of your field within three years. Within five years you'll be a national authority. In seven years, you can be one of the best people in the world at what you do.

Without a goal we are much like the man with a boat and nowhere to go. Goals give us the drive and energy we need to remain on track long enough for their accomplishment.

All you have to do is hold your goal before you and everything else will take care of itself.

The man who succeeds above his fellows is the one who early in life clearly discerns his object, and towards that object habitually directs his powers.

Get into a line that you will find to be a deep personal interest, something you really enjoy spending twelve to fifteen hours a day working at, and the rest of the time thinking about.
