Just say no
When you are asked out to do something or offered a position at work for example that you just do not want to do, say no. We need to set standards for ourselves and not say yes to absolutely everything just because someone asked. Saying no lets people know that you are in control of your life and choices.
If you are wondering when you should say no to people the answer is right there in front of your face. If you don’t feel good about doing something or even just are not interested in that offer at all, that is a strong indicator for you. Don’t waste your time on things you don’t want to do!
