Have a tzedaka box ("pushka") in every room in your home and even in your office. By having one in your place of business, the Rebbe explains, one "involves G-d as an active partner in one's business and enhances his potential to distribute G-d's blessing to others."
Any container can be used as a tzedaka box; one can also make decorating suitable containers for one's home and place of business into a family project.
