That's "In Difficult Days", which has always inspired me. I think this is really said very well.

Tell you that you should persist and work hard to do what you want and accomplish what you plan and goals. In this way, you can gradually develop a certain degree of self-discipline and have confidence in yourself. Slowly

Yes, no matter what you do, you will be very confident, and you will do everything well. In fact, what a person needs most is self-confidence. If you are confident, then everything you do will feel very easy.
