The cheapest investment with potentially very high dividend
The best investment lies in helping the right person for the right reason. The dividend might come in different forms(s), but in any form, it can’t be sweeter. I wish I could have made such investments a lot more than what I did, but today is not late to start.

My framework is pretty simple- a human is capable of doing almost anything, but a cause/idea is always limiting. So, Person> Cause in my framework.
That’s why I believe in investing in the right person for the wrong cause might turn out to be ok. Wrong cause means a cause that s/he might not be a right fit for.
I got help from strangers for most of my life, specially from places and people that I didn’t expect from. These types of help create an additional force in you because you would feel to return the favor in any form. I have also seen that the right type of person compounds it over time, which is a kind of Ponzi pyramid of help, a right type of pyramid that the society needs.
Now, the WORST investment is bashing or mocking or being antithetical to the right person for the right reason. I don’t even want to put it in my 2*2 matrix. I believe I never made this mistake (hopefully). I see many people make this mistake on a regular basis and I can only wish them luck (LOL)!
When you have time, try to be on the right side of history. It would cost very little for a large dividend.
