People always have many different roles to play. The crucial thing is to be determined to make a wholehearted effort in everything and be fully engaged in what we are doing at any given moment. The secret to successfully fulfilling a variety of roles is to concentrate fully on the task at hand and give it our best effort with enthusiasm, maintaining a positive, forward-looking attitude and not worrying.

A pyramid isn't built from the top down. The apex is attained only by laying strong foundation stones, one by one. The same is true of achieving a lofty objective. The crucial thing is to lay the first stone, to take the first step.
It is precisely when we have suffered defeat that we can determine to win and open the path to future victory.

It takes great effort to build something, but it only takes an instant to destroy it.
There are times when a victory or success can actually become the cause for future defeat or failure. Likewise, defeat can become the cause for victory in the future.

Do you give up the struggle to overcome your own limitations on the first attempt, or do you keep on with it, trying a second time, a third time, and continuing on in the challenge for the rest of your life? That is the only difference between the genius and the ordinary person.

This lifetime will never come again; it is precious and irreplaceable. To live without regret, we must have a concrete purpose, continually setting goals and challenges for ourselves. And we need to keep moving toward those specific targets steadily and tenaciously, one step at a time.

What is success in life? Who are the truly successful? There are famous and powerful people who become pitiful figures in their old age. There are people who die alone, feeling empty and desolate inside. Just what is success? The English thinker Walter Pater (1839-94) wrote: "To burn always with this hard, gemlike flame, to maintain this ecstasy, is success in life." The person who lives life fully, glowing with life's energy, is the person who lives a successful life.
When you devote yourself to achieving your goal, you will not be bothered by shallow criticism. Nothing important can be accomplished if you allow yourself to be swayed by some trifling matter, always looking over your shoulder and wondering what others are saying or thinking. The key to achievement is to move forward along your chosen path with firm determination.

Human society is made up of people who have met success and those who have not. No one knows for sure whether their life will be blessed by fortune or burdened by fate. The elation of triumph is short-lived, but those who understand that every setback, too, is only temporary and who continue to make steady efforts with confidence and conviction, can achieve truly great things. Ultimately, victory comes from never giving in to defeat.
Failure is an instrumental part of every success. Whether our life has been a triumph or tragedy can only be judged at its very end
