Why whatsapp needs a message queue?
Consider this. Alice and Bob are a couple. Alice sends Bob an important message. But Bob is offline. Whatsapp can't simply send the message and forget about it, as Bob can't receive it. So instead it goes into message queues.
Advice I heard from a psychologist:
If youβre an anxious person, do everything for fun.
Submit your resume for fun. Go to a job interview for fun. Start a newsletter for fun.
Anxiety feeds on importance. Donβt make everything a matter of life & death.
