This is a strong quote because it deals with a very common problem in society today… people who whine and complain about everything under the Sun, just because THEY CAN. Remember that no one likes a whiner, and complaining is a good way to not only make your mood worsen, but do absolutely nothing to solve whatever problem or issue you are complaining about.
Complaining also takes a lot more energy than people realize. If you were to take that energy of the everyday things bothering you, and instead pump that into remaining positive and having a thankful attitude, you’d see many of your problems completely disappear. Once something no longer gets to you, you have won. Just drop it and watch how God honors you for your decision, and watch how it improves your day-to-day life.
