Logic vs Reality

In life sometimes the logic is not in line with the reality.

If we count with the logic, if a runner wants to reach the finish line so he had to pass half way first, then to pass through half the journey he had to pass back 1 / 2 of 1 / 2 or 1 / 4 first. To reach the quarter he had to reach 1 / 8 in advance, to reach the eighth he should reach 1 / 16 in advance and to achieve 1 / 16 he had reached 1 / 32 in advance and so on, so until whenever he would never reached or passed the finish line. Would not you say?

But what about the reality in this life to reach the finish line? Yes it is easy to "take action now" or take action that is running and you will reach and pass the finish line.

That logic and reality, many do not logically possible but if we want to take action turns everything can be possible.
