“Pain is temporary. Quitting lasts forever”
— Arnold Schwarzenegger
Simplified Meaning:
When you face difficulties, the discomfort you feel is only for a short time. It's like when you work hard to climb a steep hill; your legs burn and you feel tired, but that feeling goes away once you reach the top and see the beautiful view. On the other hand, if you give up halfway, you'll always remember that you didn't make it to the end, and this memory stays with you. For example, if you are studying for a tough exam and want to quit because it's hard, you need to remember that this hard work will end after the exam. If you keep going and try your best, you'll be proud and happy with yourself. But if you give up, you might always regret not pushing through. So, pushing past the pain or challenge now will bring you more satisfaction and pride later on.
