Something that continually gets me down is trying and failing, again and again and again. I always think, "this is it", but it never is. I thought I beat it last time, and the time before that, and the time before that, but each time, I give in. I think, all of the effort that I'm putting in is for nothing, this simply must be too difficult to beat. So what's the point in trying?
The point is that you WILL get there one day. It's like making a stack of toothpicks that reach the moon. One toothpick isn't going to do it, not two, not three, not even three thousand. But everytime you try and fail, you are adding one more toothpick to the stack. That's one more toothpick that you needed to reach your goal.
And, one day, you will place the last one, the one that is stacked on hundreds of thousands of toothpicks that didn't reach the moon, but they were needed so that the final toothpick could.
