Birds want to fly the highest sky.In the same way; we want to get success in our job.Everybody are trying to the reach the goal.But sometimes we don't want to continue and give up.
If we give up; we never reach our goals.So we must continue whether we want to do it or not.Daily we must do.
If we decided to get anything; we have to get it.We must try to know the way to do.The regular doing means perseverance..So I think the key point to success is to persevere.
