Not everyone likes to work.
Some people are lucky to be doing what they love, and they wake up every morning excited to begin whatever their main activity is. They like what they do, the people they work with, and the rewards they receive for their efforts.
But this is not the case for everyone. I fairly recently became aware of the fact that you don't have to either love, or hate your job. You can just be okay with it, and have better or worse days.
One day you'll wake up and you'll just hope that the day will be over as quickly as possible. Other times you'll wake up excited to go to work. Then maybe the next morning you'll hate yourself for even putting up with everything at work.
Some days will be easier, some will be a lot harder. Some responsibilities will be simple, while others will require a lot of effort and will annoy the hell out of you.
Whatever the case, your ability to cope with everything, not complain, and just do the work, will play an important role when it comes to how you are perceived by others, and sometimes even to how well you do your job.
I've been working on different things throughout my life so far, and while I haven't done as much as others who are much more experienced than me, I quickly learned that being the person who complains all the time at work will gain you nothing but the anger of your colleagues, and sometimes even a decrease in your abilities.
I'm not gonna begin talking about how positive thinking will impact your life or anything like that, because that topic has been discussed so much already that it's becoming tiring and annoying.
What I'm gonna say is much simpler - no one wants to work, unless they absolutely love what they do. Most people would rather do something else, be it relaxing, playing games, travelling, whatever. No one wants to be working because they are forced to do so by their responsibilities.
And yet they do it. They make jokes, or try to make fun of different aspects of the job, or tell stories, or whatever they can so that time goes by faster so they can go home. But in the end, most people will just do what needs to be done and go home at the end of the day.
With this in mind, the worst thing you can do in an environment where nobody really wants to be in, is to complain. Being the only person who complains at work will quickly attract the anger and the spite of everyone around you.
Nobody likes a person who only talks about how they hate the job, how they hate their responsibilities, how they hate doing this, how they hate doing that, or how they hate the way other people do their job.
No job is perfect, and nobody at the job will always do everything perfectly and to your liking. As a matter of fact, no one should try to do everything the way you want to. Unless you're the boss, you're not that important. You have your tasks, and they have theirs. So just focus on that, and nothing else.
I've been working with all types of people in the past, and I can say without a doubt that someone who complains not only becomes annoying within minutes, but usually gets less done than others who just do their job.
If you don't like how things are at work, you can try to fix some of them, if you have the ability to do so or if it's within your power. If you don't like the way some people do their job, try to make yours independent of theirs as much as possible, in order to get to a point where their mistakes / laziness / stupidity don't influence you too much.
There could be a lot more to say about what you could do to improve your overall work experience. I'm sure that there could be a lot more I could do at my job to make everything a bit better. Everything could be improved.
But what you can do, as a starting point, is to not complain. It will not help you, and it will not help those around you. Quite the opposite - they'll begin to hate and avoid you at all cost. Just suck it up, do your job as well as you can, don't be lazy, and focus on yourself.
There will always be things that suck, and sometimes you'll even be able to complain about them with everybody else. But there's a difference between doing that and complaining all the time about everything.
In the end, the realization and the attitude that will make your life, and the life of those around you better , is this: No one wants to work, so just shut up, do your job, don't complain, get paid, and go home.
Everything else will just make matters way more complicated than they have to be.
