Think of a squirrel climbing a tree. And he gets above half way up. Maybe even three-quarters.
Suddenly, the top of the tree come into view. Man it looks ugly. But then the squirrel see another tree, which looks nicer, but at the same time, he doesn’t like leaving the familiarity of the first tree. Nevertheless, he jumps to the next tree.
And he starts from the bottom. But this tree it slippery, and the squirrel never manages to climb up it. And he wants to go back to the first tree, but is unable to. So he tries to scramble up the second tree, but it looks hopeless.
Wow, if you can decipher that metaphor, I bow to you.
