True charity is backed by energy, creativity, and imagination.  It is more than simply giving money, and should not be given in response to manipulation. There are many worthwhile charitable endeavors to which you can dedicate your time, but I challenge you to prioritize.

You can give an organization a gift of $100, yet still accomplish very little. Or, you can spend very little, and use your time and energy to help develop the basic infrastructure of the world.  This could benefit thousands of charities, and could have a sizeable impact on the global economy.  This could also lead to increased spending on medical research, and would result in many cumulative benefits.

I challenge you to use your mind to its maximum potential, and in doing so, make a measurable impact on the quality of life worldwide.  You don’t have to sell anything.  You don’t have to ask anyone for money. 

I challenge you to say no to the people who manipulate you, hoping to gain your time or financial backing.  There is a far more enlightened way to have a positive impact on society.  There is a time and a place for giving, but there should be thought and judgment behind it.
