Many of us have difficulty saying no to others. We feel awkward or guilty if we say no when someone asks for a favor. However, the less you say no, the more stress you put on yourself. This also results in people taking advantage of you. One of the most important skilles to learn is the ability to say “No.”
When someone asks you to do something for them, politely and firmly say “No.” Tell the person you already have other responsibilities at the moment and though you would love to help, you are simply too busy at the moment. Whatever happens, don’t budge.
