Academic Quotes

Smile - Len Academy

Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around - Leo Buscaglia

The most important things we can give to others are actually not expensive. In fact, we don't have to buy them with money because they are right within us.

These include our kind words, listening ears, honest compliments, our 'thank you', those beautiful smiles, our loving corrections, sincere kindness and a caring heart

In the end, it isn't the years in your life that count. It is the life in your years - Abraham Lincoln

One fact remains constant to us all, and that's death. We are not guaranteed of tomorrow because no living human is too old to die, even a newly born. Remember, age is also a number.

Therefore, let us always do good, help the poor, care for the sick and less privileged, forgive transgressions and most importantly, extend the hands of love to everyone we come across.

By doing this, we would have added an abundance of life to our years, regardless its number. Recall that Jesus Christ Himself died at 33

Smile - Len Academy

You cannot win everytime. This therefore makes defeat a part of life. However, it is the way and manner at which we rise from our defeats that determines our place among the greats.

Muhammad Ali was a professional boxer with 56 wins and 5 defeats. However, the way and manner at which he rose from his defeats secured his place in boxing history as the greatest fighter of all time

One Day or Day One, you decide - Unknown

We all intend to become great in life. However, we should also understand that it doesn't take one day to become great. Rather it takes many days of work, practice, diligence, failures and successes to become great.

My question to you is this: Concerning your path to greatness, what day are you in?

Whatever you are, be a good one - Abraham Lincoln

If you are a boy, be a good boy. If you are a girl, be a good girl. If you are a man, be a good man. If you are a woman, be a good woman. If you are a student, be a good student. If you are a teacher, be a good teacher.

I can go on and on; but the point is: You are human, so do all in your power to be a good human
