One of the most integral parts of unlocking your peace is implementing boundaries. This is something that most of us find very uncomfortable because we never truly learned how to say no. We say yes to so many different things for so many different reasons. We say yes because saying no is impolite. We say it because if we don't we may upset someone. We fear being looked at as a bad friend, family member, partner, or parent.
The problem with this is that we create resentment in ourselves. And it's not anyone else's fault because they had no idea that we did not want to do all of these things. We never said it. Then we find ourselves in need and we notice the ease that others have in saying no. This doesn't feel good. It feels imbalanced. "How dare they protect their space and their time when I never did!"
You have to live your life on your terms, the way you want. What society tells us we should be doing, our comparisons to those around us will leave us miserable. We can't try to live the life we see other people living. We don't even know anything about them beyond what they allow us to see. Be who you want to be. Mold your life.
Try to remember who you were, what you liked, what made you happy and at peace before someone told you who you should be, what you should like, and what should bring you happiness. You make the rules. Follow your intuition and feelings. You don't need anyone's opinion. No one knows you better than you know yourself. No one can know exactly how you are feeling. Learn from yourself, from your own experiences.
