My dear Siddharth,
If you really want to make a difference to society, please avoid being over-sensitive to criticism. Please don't expect understanding, compassion etc. from your fellow activists. You will need to be able to function with large doses of criticism, both constructive and destructive.
We always fall in love with our own ideas... but we can't expect others to automatically fall in love. We will have to market our ideas to fellow activists, and cut through their scepticism and cynicism until they see the merit of what we are saying.
This is just a friendly view, which applies to me as much as you and everybody else. No offence is intended.
