No-one wants to fail, no-one wants criticism, no-one wants to look like a fool in front of their peers. The remedy to failure is not to beat your self up, give in to defeat, build a wall around your personality to make you look tough,but it is like the old saying says, " If first you don't succeed try try again." What all successful people have done is fell flat ( some may have laid and mourned awhile), but they ALL got back up.
What is it that you desire to become? What difference can you make whether small or great in the world you live in? Why be someday laid away forgotten? The dream that lies dormant with you could impact generations to come. Ask Allah for direction, He will lead you into realms you never thought were possible. When you are His will there is no limit to where He can take you.
