They say, 'What goes up, must come down.' That's a bit pessimistic. And are there not spacecraft that have been sent far beyond the Earth's atmosphere? Some are reaching the far edge of the solar system and going beyond the gravitational pull, not only of the Earth but the Sun. And speaking of gravity, there are those who suspect that once we understand a little more about dark matter, we may have to completely rethink our whole idea about what constitutes up or down. You are on an up now. Why should that end? 'Look after the pennies' say the wise folk, 'and the pounds will look after themselves.' Like every piece of traditional, homespun advice, this does not apply universally. There are many situations in which people expend great amounts of energy in an attempt to achieve small economies whilst leaving far greater, unjustified expenses, unchallenged. Before putting too much energy into what, ultimately, is a matter of detail, try to stand back and see the bigger picture. From a distance, the view is inspiring. There is an old saying, 'If you reach for the Moon, you may just get as high as the top of a tree. But if you only reach for the top of the tree, you may not even get off the ground.' It sounds so wise. But what if you spend so much time, trying to do something impossible, that you have no energy left for what might otherwise have been an attainable proposition? After all, to reach the treetop, you don't need a rocket; you just need a ladder. Might you now be overestimating the amount of effort necessary to attain an objective?
