You can express your generosity in ways that are virtually limitless. This was what I wanted to convey in 'Giving 2.0' - that whether you have $10 or $10 million to give, if you identify the right opportunities and make the most of your resources, your impact can be tremendous.

Giving is a universal opportunity. Regardless of your age, profession, religion, income bracket, and background, you have the capacity to create change.

When I look at founders and CEOs like Mark Zuckerberg at Facebook and Brian Chesky at Airbnb and Sebastian Thrun at Udacity, these are companies that are creating extraordinary social good and extraordinary economic and educational empowerment, all within with context of a for-profit model.

Religion is a complex and often contradictory force in our world. It fosters hope and comfort but also doubt and guilt. It creates both community and exclusion. It brings societies together around shared belief and tears them apart through war. However, what unites the faithful, whatever their religion, is the unshakeable force of generosity.

Philanthropy is often seen as society's risk capital. That means the onus is on philanthropists, nonprofit leaders and social entrepreneurs to innovate. But philanthropic innovation is not just about creating something new. It also means applying new thinking to old problems, processes and systems.

Instead of waiting until the holiday season - when mail solicitations flood in from worthy organizations - and making a flurry of gifts because this is the time of year to give, sit down and take stock. Identify your passion, learn about it, and direct your time, mind, and dollars to aligned causes and organizations.

Of course, giving is deeply emotional. But supplementing emotion with research makes it more likely that a gift can have a bigger impact. It's like any investment. After all, you wouldn't put funds into stocks or bonds without understanding the potential return. Why wouldn't you do the same when investing in society?
