My only regret for this past year is not telling more people “No”. There is nothing wrong with telling people No. If you are tired, if you just don’t want to or if the thing they ask of you makes you feel even just a little bit off course, say no.
Compromising to be liked by everyone isn’t so great. I think I would rather be myself than say yes to things I would rather not.
Use the word No. Be prepared to give an explanation if asked, however, you do not owe anyone an explanation.
Mean what you say and say what you mean.
