Life is all about aiming at the target and hitting the bull's eye. Now, how much time it takes and how many attempts it takes to hit the bull's eye is different for different people at different instants of time. No one is perfect on this planet to hit the bull's eye every time right from the first time. Everyone has a learning curve to go through and to grow through. No one can escape it. While doing so, we cannot miss taking aims and leaping forward. Let's take the target that's challenging enough so that we reach beyond the limitations of our abilities.
When you aim for the sky, you at least reach the tree top. This statement clearly signifies that when you aim to touch the sky which is a next to impossible task, you fall short of achieving it. But the reward for aiming so high is that you land on the tree top which is still much taller than what normal people aim at. As a result, you shall stand out of the crowd for hitting such massive height. The lapse in the accomplishment of the target between the sky and the tree top accommodates the different external random factors of nature that influence our work and, hence, affect the results that we are able to achieve. These factors of randomness shall exist in the same amounts, no matter what our targets are. If we aim just at the tree top, we shall end up somewhere near the stem because the unknown factors shall, for sure, play the spoilsport.
If it's clearly understood that we need to accept the limitations of how much a human mind can anticipate, plan and take action and adhere to the influence of nature in its own style in everything we do, we can aptly conclude that we need to aim much higher than what we need to achieve. Only then shall we give our best to bring out the best from us and reach the desired destination. Only unrealistic targets have the ability to bring out the unimaginable best out of us. Hence, let's aim more and achieve more.
