The foundation of success in life is good health:

Attitude is the foundation to success. The greater the success, the stronger the foundation.

The foundation stones for a balanced success are honesty, character, integrity, faith, love and loyalty.

Education is the foundation of success[...]

It is as though something had begun to slip – as though I haven't the firm grip I had on events. – What is success? It is an inner, an indescribable force, resourcefulness, power of vision; a consciousness that I am, by my mere existence, exerting pressure on the movement of life about me. It is my belief in the adaptability of life to my own ends. Fortune and success lie within ourselves. We must hold them firmly – deep within us. For as soon as something begins to slip, to relax, to get tired, within us, then everything without us will rebel and struggle to withdraw from our influence. One thing follows another, blow after blow – and the man is finished.

Success is to be Happy in Life.

Good health is a great prerequisite of successful or happy living.

Success is when you live a purposeful life, an intentional life and creating a positive impact on other people’s lives.

The first principle of success is desire - knowing what you want. Desire is the planting of your seed.

your success in the world depends essentially on how well you harness the prowess of the body and mind. So, in order to achieve success, pleasantness has to be the fundamental quality within you.

Come, seek, for search is the foundation of fortune: every success depends upon focusing the heart.

The health of the people is really the foundation upon which all their happiness and all their powers as a state depend.

Purpose, meaning, significance — these are what make a successful life. Seek them and you will most certainly live your life out of balance, criss-crossing an invisible middle line as you pursue your priorities. The act of living a full life by giving time to what matters is a balancing act.

High ethics and religious principles form the basis for success and happiness in every area of life.
