You can say it however you like, depending on who you are and what you do. Is training worth the chance of a medal? Is the hard work worth the rest? Is kindness worth the smile? Is the thought and/or effort less than, equal to, or greater than the gratification?
Say you are walking on an old, dusty road, between point A and point B. You can’t see either of the checkpoints, A or B, and you are tired. in which direction do you go? You could go back to point A, with some benefits. You know generally what the distance back is. At A, there is Home, assurance, and ease. Then, there is point B. You could follow through your plan. You wouldn’t face the humiliation of failing, but there would be any number of miles ahead. You might run out of provisions. You might end up turning around later anyway, and that would be all that extra work for nothing. Although point B may be just around the corner, you will always have that familiar, sinking feeling that point A is so much closer.
In the end, there are two options. A)The known. Turning around after tuning around. Going back to the people who said you couldn’t do it. Or worse, the people who said you could. But you know your limits. You can definitely just make it to A. B) A chance (Or a risk, however you see it). The uphill scramble. Hope that could easily turn into disappointment.
There is still one fact that may tip the scales, though. Point A comes with lifelong regret. And there was a reason you left it in the first place.
