>I've only changed clients once, as my contracts have been very long-term

It should be pointed out that this is much closer to insecure employment than traditional contracting/consulting. No judgement from me, because I'm in a very similar position- freelance contractor on paper, but in reality, one client and a very employee-like working dynamic.

Also that changing clients is just as lucrative for contract employees as it is for fulltime employees.

You're usually expected to have 2-3 solid backup options, minimum.
