Giving becomes easier when you realize how many opportunities there are. Here are three easy openings, amongst many:
Whatever money you save on a discount, donate it. You can do this through donations or coupons. If PetSmart gives you $2.00 back, donate $2 to help animals.
Round up your change. If you pay $15.50, donate $0.50 to your local firefighters. You can do this manually, there are also apps for this. A restaurant like Firehouse Subs will ask you if you want to do this.
Every holiday, make a small donation. Donate $25 to the World Hunger Organization.
The more often you give, the easier it gets. It feels great.
