Our world has problems, and no one person can solve them. However, there is much we can do to make this a better place. It is easy to get caught up in the big things, and neglect the little ones.
Larger matters are beyond the scope of what an individual can do. That is why people get so wrapped up in them. Nobody expects you to succeed, so a mere concern is enough to get esteem.
You cannot make everyone happy, but one can bring cheer to some. Much is accomplished in not being part of the problem. Make the world better by being better and good things will follow.
Do not get discouraged by the indifference of others. Let them wallow in the shadows, while you shine a light in the night. People cannot help but be drawn to its radiance.
Refuse to be dragged into the misery that is them. Weather the storms of life. Instead of sinking below, rise above.
Others will see this, and be inspired to do the same. By shining, you encourage them to shine. And that is how one little person can make a big difference. In lighting up the darkness, you chase the shadows away.
