I want to work hard! ! Kneel down and beg you to give me some Latin inspirational quotations (proverbs)

Inspirations are real, mainly psychological efforts, not verbal appearances. If you make up your mind to work hard, it doesn't matter even if you don't have famous sayings, but you don't have self-confidence, even if the inspirational language of the whole world is in front of you, it doesn't make any sense. Inspirational quotations are reasonable and stimulating, not verbal. I hope the landlord will ponder them carefully.
