Motivational Quotes
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
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

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

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

Investing in yourself is the best life plan you can design for your future
Peace begins with a smile - Mother Teresa

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
