My wife and I were just talking about this last night. If things keep going the way they are going for me I'm hoping with increased focus on steemit I'll be in a position in 2019 to start seriously considering making the move.
While I don't like to give you a specific yes or no this is what we'll start doing in 2019 if I'm successful enough. Analyze expeneses (debt) and see how much money I need to pay for bills (house loan, car loan, insurance, etc.), what benefits will i be loosing (bonuses, 401k match, paid vacation, etc.), and finally how much money will I need to make to be able to maintain our current style of living with 2 kids.
While this may not your case at all I guess what I'm saying is sit down and lay out a plan and what it will take to execute. Hope this helps and sorry if it doesn't.
Even though we are in totally different situation you still outlined a great point. One should not do an "uninformed decision" ever, if actions can be taken to avoid that. Thanks for another perspective, for that is what i asked for:)
