When it comes to favors, do not start what you cannot sustain.
The first request always seems like an innocuous one-off. It seldom is.
It is always wise to think – Can I continue if this request becomes routinized?
A favor done once will most likely be requested again and again, until it becomes an entitlement.
“No” is simplest at the start, and progressively becomes more difficult as time passes.
