Don’t live your life and run your business as if you need explicit permission from someone or something. Build an amazing business that’s centered on you providing tremendous amounts of value to your clients. In exchange, you’ll be rewarded with clients who respect you, clients who want to work with you and you alone, and clients who might — just might — be willing to pay you $20k a week (but first, you need to figure out and communicate why they’d be silly not to).
Note to self: give users and clients all the value that they can extract from you. Make it so good that they find it hard to let you go, only then you can start charging what you wish it be worth.
