You never know what efforts you have done to help people will have any results, but every time you work hard and help others seriously, you will find that at a certain moment in the future, you have paved the way for you to do something unintentionally. Every time I encounter this situation, it reminds me of what Jobs said, "You can't connect the dots looking forward; you can only connect them looking backwards. So you have to trust that the dots will somehow connect in your future." Thank you for your help
