Encouragement is something that is offered to provide support and a boost in the morale of the person. If you are attempting to take a very difficult and complex college course then you may need encouragement to stick with it and finish the course with a good grade. Fans in the stadium who cheer on the football team when the team is losing are offering encouragement to the players.
Let your smile change the world, but don't let the world change your smile.
Success usually comes to those who are too busy to be looking for it.
Every situation isn't the best. But, you can make the best out of every situation.
