I feel that the client/designer relationship has to be a good fit, it’s like dating.
Maybe some of my clients who I love and get on with, would not work well with my friends in the trade and vice versa.
I’ve worked with sourcing agents that I loved and did a great job for me, that previous bosses of mine have hated and slandered as being no good. I’ve worked with clients and bosses who I totally ‘get’ whereas I’ve met people who have had difficulty with.
It’s not one size fits all and I’m now a lot more relaxed and a lot less paranoid about things and am happy to say no if I am contacted by a potential client that I feel either won’t be a good fit for us or who I suspect will drive me mad (and the feeling can end up being mutual!)
