In every work enviroment there are some people that might be a little too much on you, you are overworking, get stressed and frustraded. Here's some thoughts for you.
Every "no" that you tell to someone is a "yes" that you tell to yourself. So be SELFISH. Sometimes you believe that you are helping or being nice ou or cool saying YES all the time, just forget it.
You're not helping anyone if you are not 100% and let me tell you more, you are going to be used as stepping-stones or acting like a fool, after all, everyone will know that you are the guy that says yes to everything. This will to please to be recognized, is due to your fear of being truly yourself, but guess what comes next.. FRUSTRATION.
You are not going to be recognized as you want to, you're going to be frustraded and asking yourself where did you go wrong. I know that because i was that guy.
Women learn early that they need to say "no", men learn early to receive some "no". So if you're a guy and want 2021 to be the best year of your life LEARN HOW TO SAY NO to things that you don't want to do.
