I think something that you need to get better at is being strong emotionally. The first reason is that you will be critisized by your fellow workers. There are just some people that like to get on your case about things, and you will have to deal with that.
Also, your boss will be telling you things harshly or yell at you if you do the wrong thing. You should be prepared for that. Some bosses can have a bad day, or are grumpy.
ANd lastly, to deal with stress. SOmetimes work can take over your whole day and how it happens. Don't let it control or get to you. Take a deep breath in and out, and shrug it off. We have to be strong to make it through the day.
These are teh reasons why I think, you should be strong emotionally to go to work! But don't forget to always be ready for work too!
(i hope this isnt like a huge essay if so i would add some more detail but thx!)
