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.
Inspiration comes from so many things that it's hard to define what that is or when it happens. It's always been a strong feeling that comes over me in a given moment, and it feels like hope, desire, strength, magic, excitement. A supreme motivation to create or do something special. To win for love.
The motivation is really to say people can find the game of getting involved interesting and find the problem and really have the passion and the enthusiasm to solve it and move forward, but that's all I know.
