The saying, “courage is not having the strength to go on: it is going on when you don’t have the strength. So it can be clearly understood that it is not the problem which stops you, but the attitude towards the problem is causing trouble. So it is the power of mind which makes the problem smaller or bigger. It is said that it takes courage to grow up and become who you are. So can courage with perseverance is essential for success?

Yes. It is.  According to our ancient literature even a trembling stick by the wayside which is if no great use can be used as a post to tie an elephant when it acquires strength. Similarly, a man who can free himself from his base nature and gains strength then his life will be similar to the pole which can control an elephant. Hence perseverance with courage can give extraordinary power which can be developed by manipulating your mind.
