"Nothing lasts forever", I find that very true and enjoyed reading your piece. I find a lot of things come in waves: energy, sound, and life itself. Every good and every bad thing has a beginning, a middle (or peak) and an end. That light bulb started to light up years ago and to remember that nothing lasts forever or that events, situations, come in waves, all come with beginnings, middles or peaks and ends helps to get through difficult times - to show that it won't always be bad or negative, and that we should appreciate and enjoy the good times as long and as much as we can.
