If you’re an introvert, try make conversation with strangers on the plane, stay late at company functions.
If you’re an extrovert, try set aside a few hours of no social interaction, give yourself some peace-time.
If you hate detail, get stuck into the detail.
If you hate sales, pick up the phone and do some sales.
It’s not comfortable, but you never know what can come of unusual circumstances.
At the very least you’ll be exercising muscles that you may just need one day.
Whatever is uncomfortable for you, try do it.
