While you're busy making money, don't forget that there are those in need whom you can help. Even if it's only in small ways, give. Give your time. Give your money. Give your prayers. Give your gifts and talents. Do something to improve the world.
There is a saying that the poor will be with you always, and to some extent that's probably true. Because of natural disasters or war, there will always be people who need some help. Also, because some people just don't have a desire to better their lot in life, they will remain poor. However, for those who just need a little boost to improve their circumstances, there are ways you can help.
What I'm referring to is the work that Heifer International does around the world. They work with individuals and families in the US and in foreign countries to educate them and give them a start to a self-sufficient life. They teach sustainable agriculture, offer a beginning to farming that's right for their particular area, empower women, and guide families and communities into a life of success. They teach people to share with others so that communities benefit.
There are a number of business ideas they have for people who are only willing to work and make themselves a success. From farm animals to bees to bunnies, these folks could probably show families how to use stainless steel drums to store water as well as store feed for whatever animals they are raising.
If you're thinking of giving back, this is the place to make the most impact globally.
