Merit is often an obstacle to fortune; the reason is it produces two bad effects, envy and fear. (Traditional Proverb)
Inferior men do not begin undertakings for fear of difficulties. Average men begin, but desist once difficulties appear. Men of superior nature never give up until they achieve their ends, however many the difficulties that appear. (Traditional Proverb)
To turn an obstacle to one's advantage is a great step towards victory. (Traditional Proverb)
