When is the right time to fire your client?

How do you know when a client is a good fit?
You are willing to put aside time to work on a project for them
You feel compelled by the cause and are passionate about the impact
it is making. You are fueled by every conversation. Every time you
speak with them you are motivated and energized, and feel even more
creative. You think of ways to help them at all times of the day
You are on the same wavelength about a lot of topics and are
willing to go the extra mile for them, even though it’s not part of
your mandate

How do you know when a client is no longer a good
fit?
You feel completely drained after interactions with them You
work overtime trying to please but zero acknowledgement of this or
apparent appreciation It no longer feels like a partnership but
more a knee jerk response to everything you do with them Every
conversation is about them and completely one-sided, in fact you
begin to wonder, did they even hear what I said?
