Motivational 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

The first problem for all of us, men and women, is not to learn, but to unlearn - Gloria Steinem

The act of unlearning is an excellent form of learning. Infact, you will need the skills of unlearning if you intend to become an expert in your desired field.

Do yourself a favor by unlearning, learning and re-learning on a daily basis

If you don't design your own life plan, chances are you'll fall into someone else's plan. And guess what they have planned for you? Not much - Jim Rohn

There's something special about you. It doesn't matter whether you work for a company or someone; what matters is the amount of investment you've made on yourself.

Investing in yourself is the best life plan you can design for your future

Smile - Len Academy

Peace begins with a smile - Mother Teresa

Never underestimate the power of your smile. It can lift up the depressed, improve the mood of the downtrodden and even discourage a suicidal attack. Also remember that your smile makes you more beautiful

Smile always for your own good and the good of others

The only person who is educated is the one who has learned how to learn …and change - Carl Rogers

To perfect your learning process, you must learn, unlearn and re-learn. Infact, we all need to learn how to unlearn those vices we know about ourselves.

Do you know that seeing the devastating consequences of vices (perhaps in movies or real-life) can initiate the unlearning processes in one who does such?

Start where you are. Use what you have. Do what you can - Arthur Ashe

Start now. You've got all it takes to achieve greatness, so no environment can limit you. Just begin something, give in your best and don't stop.

Remember, don't stop giving your best if you truly desire greatness. Nothing can stop you except yourself

He who opens a school door, closes a prison - Victor Hugo

Education goes beyond the four walls of the classroom. Always attempt to promote education at every chance you've got. Begin with your family, friends and those you interact with. In addition, do not forget to educate others with your words and actions.

Close a prison door by sponsoring the education of someone in your lifetime
