According to this quote by Anthony J. D'Angelo, if a person has time to complain about their situation, they also have time to do something about it. For instance, a person may complain about not having enough money, but has time to talk on the phone complaining instead of improving their skills or finding another job.
There is a solution to every problem. Most of us take time for granted when it is the only valuable resource we have. Instead of complaining about issues, we should use that time to find solutions to fix our troubles. So, we can focus on enjoying life.
