adversity :)

To me this quote means you either get over your problems and succeed anyways or you dont do anything and sit in a corner and cry because you dont want to take the time to realize thats it just one event inyour life and theres plenty more things to happen to you. If you get over adversity you have more opportunities in life.
Take Abe Lincoln for example, he ran for president multiple times and he failed at first. If he would have just gave up hope what would the world be like today? He got over his problems and continued trying anyways and eventually he suceeded. Theres also Steve Jobs, he lost his job butthen he made a computer in his garageand started one of the biggest computer companies in the world. There's many great people out there who have suffered hardships but then achieved great accomplishments.

I agree with Keke, this quote to me means to get over obstacles/ problems
