I used to think that I had to be this well-put together person for people to like me. For people to be my friend, people to like me, to find someone who might want a relationship with me. I thought I couldn't be too far "out there" for people to understand me. Now I understand that others opinions don't matter...AT ALL.
Who I am now is someone who will compete with her friends to see who can make more chins appear. (I won of course). I am goofy and make a fool of myself around others. Yet, I am happy and I enjoy making other people laugh. I stopped caring that others may think I am weird and don't necessarily want to be in my life. That is fine, that is their own opinion. It may hurt a little, but when people leave, you value the ones that stay so much more. It is okay to learn to laugh at yourself. You have to in order to let somethings go.
There are times where I made such a fool of myself in public. Yes, at first I was felt so embarrassed, but now I think I would do it again in a heartbeat. I love it. Learning to laugh at yourself can make you grow. You realize that mistakes happen, and they will continue to happen. You learn from your mistake but you should not dwell on it. Laugh about the silliness of it and move on. On the other hand there are mistakes that should be taken seriously but it's important to learn the differences on your own and not have someone tell you.
Laughing at yourself is being who you want to be and expressing that. I have danced goofy at the bar, I wore a adult onesie around on a random night, I sing (completely) off-key in public, yet I can laugh at the fact that I look crazy to other people. I have learned to be happy with who I am and whoever decides to come in my life. I am happy about that, and those who do not are not meant to be.
