To maintain the highest level of ethical standards under any given circumstances is the advice received from my father since the beginning. Adhering to this though, has put me in difficult situations at times, but nonetheless it has always been beneficial in the long run.
In my professional career, the best advice I got is from my current boss who said that nobody has a copyright over any idea. Ideas can be generated from anyone. There are times when ideas generated from an executive are far more effective in the implementation phase than an idea given by a director.
This policy of free flow of ideas has been inculcated in our organisation and has indeed resulted in the significant growth of the company.
