“Stones and sand are heavy, but trouble caused by a fool is a much heavier load.
If there is something or someone in your life that is causing grief, then you need to evaluate how you are handling it. These things can cause an aching down in your bones and make you sick. It is is something, then get rid of it as fast as you can.
If it is someone, then it needs to be handled differently. Try to help the person to help themselves. If this cannot be done, then you need to distance yourself from them.
You can love and be kind to people without them destroying you.
