Life is like a blank canvas; whatever you write on it will mean something. So never say that life is meaningless. The worth of your life depends on the meaning you provide it. Thus you should strive to attain the maturity to make your life worthy of bringing about a change in your own self as well as of those around you. This quality of bringing about a change is the biggest one you can attain.
Life is a process where one keeps growing. As we grow, the number of years keeps adding into our lives. However, most of us only keep adding years to our life; there are very few who grow by adding life to their years. Remember that life is what we make of it; so we should try to make it fruitful by adding life to our years.
