“If you get stuck in the memories of those times, you won't be able to appreciate all the fun that's happening right now. So don't think 'That time was fun', instead you should be thinking 'That time was also fun'. The really fun things can't be compared with one another. Ah, but here's a piece of advice: being able to find the fun that's happening right now, that is the best way to enjoy the present. Because of that you should be try your best to value the present, since it's going to change, sooner or later.”
