Yeah. Everyone is unique. Different people has different skills. For example fish can swim well while crows can fly. If the fish tries to fly because the crow can fly, he won't be able to fly. The same goes to crow too. If the crow tries to swim, he won't be able to do it. If the fish will be demotivated because he can't fly that is meaningless. So he should try to develop the abilities that he has. Not to develop the abilities what others have. So if we are unable to draw maybe we can sing well or dance well or there is something that you can do better. We should always try to develop our own skills while keeping in mind that we are unique :)
