I would like you all to keep this phrasing as a reminder, as the opposite can quickly lead you into a slippery slope of bitterness and negativity on you and the people around you, unless you remember to get a hold of yourself.
To set the stage, I had an irritating situation at work, yesterday. The work that I thought was done by one of my co-workers, the day before, came back for me to deal with. I was not pleased with that. It didn't help that this particular co-worker's shift only started some hours later, so I was left with this mess without any answer to why it wasn't done the day before. So I worked on while wondering what the possible answer to this question was. Minute-by-minute, package-by-package, these possible answers turned into assumptions, doubt and ignorence about this individual. This in turn gave way to some bitter mood, overall very negative intuitions that I began to feel about other people in my life; and thoughts about how "they would go against/not care me in the future if I was ever down".
These depressing thoughts stuck with me for a few hours, until I realized that all of this started, because of a relatively small thing that really only had a slight impact on the workday, and that I should stop this bitterness, so it wouldn't effect my other co-workers. Took a little while, but I finally found some peace of mind and regained some positive spirit for the rest of the day.
Now, why am I writing all of this to you? Simply put, I don't want you to become bitter. Not that you should force happiness upon yourself, but it's too exhausting being bitter about meaningless stuff. The world is full of shit to make life dull, and it's too easy to fall into the trap of an unpleasant mindset than staying in a positive one. Remember that there's more joy to life than animosity, but you have to work on finding and keeping that virtue and meaning of life.
Also, I think that this, too, needs to be stated:
Take a break with the self-depricating humor
Or any form of demeaning remarks on yourself or on people you love. I'm gonna echo the sentiments of my buddy Denshi on this topic. Even if it's in good spirits, the more that this type of humor gets used daily, it can then lead people into being more pessimistic, less secure about their skills and believing that they will never be good enough. Which again, I don't think that you need to add more unneccesary negativity into your daily life.
And always remember: If you can see yourself in the mirror and find any flaw to fix or room for improvement, don't ask when. Start working on being a better version of yourself. It will be brighter in the long run.
