Sometimes at work it's difficult to say no because we're paid to be there and do a job function. Saying no to friends and family can be very beneficial though as blindly saying yes (usually out of a feeling of obligation) can be draining on time and other things. Boundaries are important for every individual to learn.
Setting limits is essential to avoid making commitments out of obligation.
That's right and with family and friends it can get out of hand, people feel obligated I guess, and suffer personally for it at times.
Yes, and there's also the other side: many people get upset when they're told no to a request or favor, and that's when they give in out of obligation.
Yep that's right too. I guess a person needs to determine whether to prioritise themselves and when to prioritise others, a mix of each is required depending on circumstances.
