I wanted to clarify what I said yesterday about saying "no". The person who asked it was worried about hurting others people's feelings when you say "no". This is understandable and something I used to think, too. There are a few layers to this. One is the fact that you can say "no" in a benevolent way that makes the other person understand that it is ok you cannot do it. For instance, if someone asks you to hang out but you have an important deadline, you can say something along the lines of "Thanks for the invite but I got work I need to get done." You are not saying "no" yet you are conveying that you are not available. Second is detaching yourself from other people's reactions. I am not saying to be apathetic. It is recognizing that you can only control your actions and emotions, not the other person. Third, when you do not say "no", you are compromising on your goals and time. You are allowing other people to take precedent over your energy. When you say "yes", people will keep coming to you and eventually, you will be spread thin. I understand this sounds extreme and I am not saying to shut out everyone. It is all about choosing what serves your prospects for the life you want. Like jakobi said, he doesn't party, he goes hiking. Not everything must be rejected, rather, evaluated based on your circumstances.
