Money and time are huge things here that we have no data on. 1) Do you have enough money saved up to support your family for two years and to support the launch + operation of your idea? If not, then no problem - just do it part-time for 2-3 years until you can go full-time.

2) Are you willing to commit 20 hours a week part-time or 60 hours a week full time? If "No" to whichever is appropriate then I'd say that you would find it difficult to succeed regardless of other circumstances.

Best of luck to you!
