Every company doesn’t have to be a perfect place where everything runs smoothly. Instead of freaking out, you can simply learn to accept that your company is not that great and try to adapt yourself to unplanned situations.
Instead of panicking or worrying about what will happen at the next moment, you can simply have a calm and relaxed attitude. Come what may, just face it and keep working towards your goals.
Get a good team going to work for you and under your guidance in order to deal with the work pressure. Have some fun laughs in breaks and don’t promote toxicity further at least in your team even if your office is full of nasty people.
