I remember listening to one of Ariel's lectures on Youtube some time ago where he said that if you want to get something in abundance you should offer some token amount of it to others in advance and then claim it tenfold. Recently, I was working a job involving helping people, but on few occasions I really went out of my way to do more and solve vulnerable people's problems that weren't necessarily mine to solve, afterwards I claimed all the help I will need from others in future tenfold. Imagine, a month has passed and I am now involved in some personal project and every person I approach for help offers me assistance ungrudgingly and that free of charge even when the charge would have otherwise been expected. Apart from that law, the name of which I don't recall at the moment I believe that the law of detachment played its part too, since after claiming my share I stopped thinking about it. Truly amazing.
