Plan out a year or two with your budget; first thing is to stop any worry about the $$ side of life (knowing it`s real, but removed from your mind for now).
Go off into the woods/beach/library ... crawl into your head, skim your joy and sorrow, skim current knowledge and revisit old classics on "what`s life" and see again what makes you (and your family smile) ... be "alone" as much as you can at times [prepares you to "invent" as that`s a solo thing and most of your current "buds" can`t afford to do what you`re doing right now].
Plan to fail; plan to revise and try again ... with time you can change your life, but if you jump, rather than ease, then plan to make multiple jumps. Find a "group" (SuN) where you can "share/vent" your emotional side of what`s to come with the unknown; again, this is a "solo" journey for the most part and while you will need some support (and partners are great things in my book) you must be your own rock and board as you`re the one writting the checks.
Give yourself about 6 months of "me time" (it will seem like a lifetime) to figure out what makes you feel good and what you want to be doing; I`ve lived several successful lives, but most came with the overriding "fears" of soft science (design, mkting, things without quarantees) and so I decided that I wanted to have a physical product; something that wasn`t a matter of spin or measurement ... it`s far from easy, but it works for me not having a product that people can "improve" by changing a color.
I guess I could go on forever, but basically I`m saying know that you have the time to cut down the forest of you life as it now exisits and then watch it grow back; only this time treating it more like a garden and landscaping it to match the vision in your mind (naturally you can also stay consulting and connected to your "past life" or go to Mexico too!)
