During the message from the flight attendant, prior to take off, they say “if you are sitting with someone who needs assistance please put your oxygen mask on first, then help them”.
This is great advice for life in general. Before you try helping others make sure your life is in order..
There are many people giving advice for how to do things when they have no clue themselves.
I realize it might sound selfish but if you can’t help yourself, why do you think you can help others?
Have a great day!
