There are so many things to choose from in life. Anyone whose achievement is exciting can often be referred to as a rare Gem but the concept herein is quite different. A rare gem in my writing are the essental things we need in life especially those items we cannot live without. Some of them are branded perfumes, Lotions, Clothings - Dresses and even our Bra. Can someone tell me why the last item is essential? Let's take a walk and sometimes walk-run. Exercise is an essential tool for long life and so we need it and we must do it as often as time permits.
Can you now figure out the hidden concept?
