Every noble work is bound to face problems and obstacles. It is important to check your goal and motivation thoroughly. One should be very truthful, honest, and reasonable. One's actions should be good for others, and for oneself as well. Once a positive goal is chosen, you should decide to pursue it all the way to the end. Even if it is not realized, at least there will be no regret.
