If you’re having a tough time at work, remember to not get overwhelmed to the point where you no longer notice all the good you have in your life.
Notice the family you have. Your spouse, your children, your parents.
The supportive friends you have, at work and after work.
Notice the privileges you’ve had, such as being able to have an education, have enough to eat, and having a roof over your head.
Notice them and be grateful.
Realise that you are actually already happy if you paid attention to the right things.
