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

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