There is some self-interest behind every friendship. There is no friendship without self-interests. This is a bitter truth.

Before you start some work, always ask yourself three questions - Why am I doing it, What the results might be and Will I be successful. Only when you think deeply and find satisfactory answers to these questions, go ahead.

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.
