The great Mahatma Gandhi said
"be the change, that you want to see in the world."
With due respect to Mahatma Gandhi, I want to say it is easier said than done! The toughest thing in the world is to change oneself, no matter who you are and how much education you have. We are all wired in certain way beginning with the family, society friends and others who knowingly or unknowingly influenced our lives. If it took twenty to twenty five years you took to become who you are today, it is ludicrous to expect to change oneself in a day, or a month or a year! With conscious efforts one may be able to make some changes in five years. How many people are willing and able to invest five years in changing oneself?
But there is a Catalyst that makes change possible, though it is not the most desirable one! That Catalyst appears in one's life as a tragedy, misfortune, or a life threatening event. These life changing events like the loss of money or a loved one or one's reputation leads one to internal soul searching which results in total transformation! If you want to change yourself, take baby steps and allow the time it takes to sink into your consciousness. Be prepared to fall, but muster courage to get up. Be persistent!
