Give directly to your family and neighbors who need help.

Giving to companies who turn around and give to charities isn’t true charity. They are using your money instead of their profits.

And don’t seek awards and recognition for your good works.

Excellent Advice.

If you’re a teacher, pay attention to the supplies and items your students bring to class.  Is there a child with obviously worn out supplies?  Make a gift of a new or very gently used item, like pencils, erasers, pencil case, book covers, etc.  If you can’t afford it or know the parents would be offended, do something like bring a healthful snack to share, or bring a large needle and dental floss to sew up those ripped seams in a child’s backpack.  Wait until the class is in P.E. or elsewhere.  Keep your mouth shut!
