I disagree with a lot of this. However, I do value your comments and I'm glad you wrote them. This is just another perspective.
> - It's a relationship like any other, and you earn each other trust through your interactions over time. So you need to be extremely reliable and responsive if you want to be perceived as trust worthy;
Trust does develop over time. But it's not something to worry about. It's something that happens naturally. Being reasonably reliable is important but set reasonable expectations.
> - If something bad happened, be transparent and the sooner you say it the better. It's extremely uncomfortable, and you'll try to delay it because you don't want to say shit happened, even if it wasn't your fault.
It shouldn't be uncomfortable to be honest with people about what's happening. If you are uncomfortable then there's likely a power imbalance. You don't have enough clients so you are worried about making one client unhappy.
> - Never bring up a problem without a solution, or a potential solution, or a recommendation for a solution. No one wants problems, we all have plenty of those. Even if it's something out of your control, you should always spin a solution for it.
I think the real issue here is that clients want people who are able to exude the confidence that they can solve problems. I see no problem outlining a bunch of problems that need to be solved to a client.
> - Always reply, never leave someone hanging;
Agreed. But I read a sense of urgency here. No need to reply immediately.
The missing piece here is that your skills are in such high demand that you don't need to act like a servant to your clients. If there is mutual respect you will get paid a lot more. Since you are new to this it will take time for you to appreciate this.
