Biggest lesson you need to learn - When things don't work, don't change the method, but dig deep. I have seen people will not wait to dig deep. They will look for some other solution. When you approach me with that kind of 'use and throw'. utility attitude, you will never be able to explore my depths. Balasanths know hen something not working, they just need to spend little time over it. That's all. Will persistence without changing the methodology or the Guru. That's all!
