As long as one is following the right way, one should never be concerned about the reproaches of those who like to find faults.
Any day we wish we can discipline ourselves to change it all. Any day we wish; we can open the book that will open our mind to new knowledge. Any day we wish; we can start a new activity. Any day we wish; we can start the process of life change. We can do it immediately, or next week, or next month, or next year.
