Don’t always be giving.
Because there are greedy people who always gather to themselves and give nothing in return.
I once drew a sketch for a podcaster for free. After I emailed the data of the sketch, he ignored my email and didn’t give me a testimonial he promised to give. Six months later he emailed me and asked me to draw, assuming that I would do so for free again. Of course not.
Giving is a powerful and faithful act. If you do so with sincerity for a truthful person, it works for both of you. But the fact is, not everyone is trustworthy. Throughout our life, we keep learning a lesson from interacting with greedy people.
