If there’s one thing that now-me would urgently tell past-me, when starting this whole self-employed business, it is this:

Beware of „cost“ focussed clients,
seek the „investment“ minded ones.

Adapt your communication accordingly.

If your services are seen only as „cost“, no fruitful and growing relation will come out of it - and with those clients, no matter what you do, it will not be honored.

If your services are seen as an „investment“ on the other hand, there’s a clear mindset that you will provide added benefit, and this is a whole different mode of operation.

(this orginally was a short burst of tweets, maybe I'll add some more thoughts to this post later.)
