With giving season upon us, we started asking ourselves how we can make bigger impacts — not just at the end of the year — but perhaps year round? We all have causes we care about, but when does it make sense to take donating money, time or resources a step further? When does it make sense to start a charity or not-for-profit organization of your own? To help us answer these questions, we’re sitting down with Scott Harrison, founder and CEO of the non-profit organization charity: water, which focuses on the global water crisis and the world’s 663 million people without clean water to drink. In Mailbag, we answer your questions on healthcare plans for people in their 50s and 60s, forgotten stocks and freezing and unfreezing your credit — which you can now do for free. No more excuses — and more details in Thrive.
