Remember to separate your work from your life, especially when it comes to dealing with people.
Whether you two are friends in the beginning, or want to be friends through work, don’t have these ideas. Unless you have a big enough background.
You have to know that once it comes to work, there will be competition. Even if you want to be a “salted fish” quietly, you just want to do your job well, others will regard you as the enemy. This will never be avoided.
Before that, I always believed that as long as you are kind to others, you will get the same sincerity, but later, I found this idea very stupid.
This is a very realistic problem. You never know who will hurt you when it comes to interests. So remember to be selfish.
