We as humans are always wanting to be 'better' in the sense of kindness, and morality. However everyone has at least one flaw, and you shouldn't be afraid of that. Some of these flaws can range to things like taking to fast, talking to slow, talking too loud or quiet, being unintentionally selfish, turning the conversation to more about you, and the list is really endless.
And that is okay! We are allowed to have these flaws, and even tho some of us might not notice them right away, once you do it is important to try and work on them. I for one have many flaws and strive to work on them every day. Now, I may not be the best at actually fixing them, but at least I am doing something about them.
I try to stay quiet in conversations now, mostly due to the fact I unintentionally interrupt people, and I talk way faster than others so some words mix together and it sounds like complete nonsense. I fight the urge to interrupt people on a daily basis, and I do not mean to be rude when I slip up and do interrupt.
I believe it is just that when I was in high school I was more on the shy side so anything I would say would not truly be heard in a group. At least that is what I felt like, mainly because no one gave me that recognition of 'oh yeah I heard you'. I also have a terrible memory so during a conversation I'll think of a really good thing to add into the topic but by the time they look at me to speak if at all, I end up having lost the thought.
This is just a few of my personal flaws that I notice, and try to take note of and fix. I have many more and most of them revolve around me being so hung up in past events, and one of those from that is that I constantly bring them back up in conversations, mostly about things that have really impacted me a person. I have lately been better at not bringing them up but they still wander around my mind.
Regardless, having any type of flaw(s) is okay. Acknowledging them is good, but what you do after realizing you have these flaws is what really matters. Granted that no one really likes someone who is in a sense 'perfect' or 'flawless', Some of the best book characters are flawed and that is what we like. Having these flaws shows everyone that you are still human and that just because you may have a tendency to overreact to something, or if it is as simple as not being so loud when you speak, it does not mean you are bad.
Embrace your flaws because in a way they make you who you are, and they also give you something to work on about yourself. But doing nothing is one of the worst things you could do.
