I know from experience and can tell how hard things have become, I can say, for a fact that most times, we become tired and do not feel like pushing, in fact, we feel exhausted, and lifting a finger is a hard job to do but, whatever and however we feel each day, we should never stop climbing.
Most days, we return exhausted but with nothing to show forth for it, many times we make plans from the beginning of the year, hoping to achieve those little plans/goals but unfortunately, we end the way with no plans or goals achieved, it is a reminding to keep climbing.
Even when we feel we've achieved the goals, we set for ourselves, don't relent effort, keep climbing because you never can tell what life has got installed for you.
Never stop climbing, keep climbing, and keep aiming for the top, it doesn't mean you are not contented, it means you aspire for more and there is nothing wrong with that. Even in situations where things aren't working perfectly well as you planned, keep climbing, and don't relent in the effort.
One truth is, that the top of one mountain is the bottom of the next, so imagine if you are celebrating and have decided to stop when you get to the top, only to realize that where you are standing at the bottom of the next, it is wisdom to always aspire for more.
Keep climbing, even the richest man currently hasn't stopped climbing, every day he comes up with new developments, new strategies, new plans, new goals, new techniques, and technologies on how to earn more.
I know how tiring it is and how tiring it gets, take a break if you have to, rest if you need to, but never stop climbing, keep climbing.
