Do you prefer email or phone to organise plans with friends or even a business contact?
Most introverts out there will naturally say that email is the better way to avoid that contact with someone that they don't know well.
I'm here to say that using email to make plans is frustrating, annoying and a waste of time. Something that could be accomplished in a 90 second phone call can by the "convenience" of email take three days.
Whenever you want to organise something with a friend and I know that because you are an introvert that it will be the singular friend, not friends, just pick up the phone and do it. You will thank both me and yourself when you do. It is so much easier.
Next time, ask yourself:
SHOULD I USE THIS?
