This is my journey. As long as always follow the trail, I shall reach the destination at the end, be it easy or rocky, bright or dim, ascending or descending.
There are always twists and turns awaiting me somewhere, or I may pick my pot of gold on some of the days, otherwise it is just one ordinary day to me.
This is the journey which I have chosen.
And this is the journey of the colony of ants. They have their own invisible trail which they will follow by the rule.
They have to ascend or descend along the journey which is not much different from mine.
They may occasionally stop for some checking, but the travel will continue.
Same as mine, just keep going on.
