We should all have a good attitude. As long as we work hard, do it with our heart and pay, we will not live up to ourselves, and we will certainly gain something. For example, Allen said that by making this film, he will learn something, absorb some energy, and then apply it to his next play, which is beneficial to him. Of course, his efforts may not be rewarded in time now, but these gains will be applied to his future efforts, so maybe one day his efforts will be rewarded in time.
I don't think it's normal to pay or not to return, but my efforts will definitely make me better and stronger, which invisibly increases my chances of getting rewards in time in future efforts, so I think as long as I pay, there will be rewards, some in time and some in time, and only if I work hard to a certain extent can I get rewards.
Therefore, I hope that each of us can work hard and live hard. As long as we work hard, life and work will never fail us, and it will definitely give us a big surprise at some point in the future, because that is the reward of our accumulated efforts. They may not pay you back in time when you pay a little, but they need some persistent efforts to get a big return. I think as long as you pay, you will get something back.
