I am about to embark on the same journey. How did you leave your old job? Did you get let go/fired or did you tell them you were leaving to explore new opportunities...?
I am in a complete golden handcuffs scenario, and the work is so slow and boring I want to blow my brains out...
Going freelance was something that I had been considering for a while, and had been doing jobs on the side as time permitted. I actually hadn't planned on making the jump as soon as I did, but it was obvious that I wasn't happy in my full-time position...and the conversation with my boss came up out of nowhere...kind of the elephant in the room scenario...and we had a heart to heart that was probably long overdue.
Let me just say that if you're an asset to your company, it's possible to create a very comfortable exit where everyone wins. A soft landing for you, and quality work for them. It all depends on where your head is. If you're completely miserable, and don't even like the place where you work, things may not work out like that...or you may not want them to. But if it's just a matter of not feeling challenged, or wanting to carve your own path, your current employer could be your best client. And I think a certain amount of respect comes with unlocking the handcuffs and doing it on your own.
I really don't know if that helps or if I even answered your question. But I think the important part is to be confident that you can make a go of it on your own. That gives you an advantage. The knowledge that you don't need to be someone's employee is more empowering that I can explain.
Hope that helps. Good luck man!
