To see the potential of gains you need to go back to Jan 2007 when the index touched 6,000 points. We are still under 4,000 points. Then although the usual zig zag of the curve will remain, get your focus on the next 1 year of 2. The profit taking and demand supply dynamics will always lead to corrections, but for me if the price goes down, well I can increase my stake and if up then I won't mind the profits.
Time is money, so money is time. Money saved is time gained in reverse! Money stores your life’s energy. You expend your energy, get paid money, and store that money for a future purchase made in a currency.
