… was hired by two different former clients.

One from six years ago.

One from I don’t even remember, it’s been so long.

In both cases … they contacted me.

In both cases … there was zero need for me to prove my capabilities.

In both cases … the “proposal” consisted of a few informal emails back and forth.

None of this happens, though, if you don’t invest at least some of your time in maintaining connections with past clients.
