Hey there, Hopey. While I agree with you that limiting expectations especially in the aspect of salary increment is important, sometimes we just cannot help it. Imagine a teacher who works from 8am till 5pm and gets paid 30k a month. Surely, the feeling of dissatisfaction will constantly seep in. However, it'd be best if we controlled it. As you mentioned, if we don't, we might start hating on those around us.
Thanks for stopping by, love.
