Subtlety
Subtle changes have the power of making a huge difference. People don't realise it at the time, but it does.
To Illustrate:
Take a point and draw a line. Now take a 1 degree deflection from the starting point and draw another line. Initially the paths of both lines seem similar but as you go on extending the line the divergence is apparent and huge. And the longer you draw the lines the more the deviation.
Let us assume you are flying a plane from Bangalore to Delhi. If you have a 1 degree deviation in your route, you will find that you land up in Haryana instead of Delhi. The same plane, if it was flying from Delhi to New York would end up in Washington DC with such a small deviation.
Even in absolute terms the difference is subtle but the outcome is wildly different.
Planes do not fly in straight lines, and neither is life a straight line.
Like a deviation can make a huge difference in the long run; so can a nudge or a learning born out a conversation. The effects of these subtle changes can make the difference between success and failure.
Surround yourself with people who can give you the right nudge and push you in the right direction. Gather diversity of thought from a variety of people. They average themselves out and you tend to arrive at good decisions.
A nudge, a push, a casual conversation can change everything.
