Thats an impossible question for someone else to answer. You just have to figure out your finances, job situation and your time situation. I would not say "just do it" as that might be very irresponsible considering your life situation
...or it may be a great thing!
Will there be enough money in the kitty to cover your cruising expenses? Insurance
, berthing, food
, terrestrial travel to sight see once you get there, upgrades? Do you have a mortgage to pay?
Do you expect to be able to get your job back when you come back to a terrestrial lifestyle? What other means of employment
opportunities are there or do you have enough money now to retire?
Do you have kids
? Do you feel comfortable home schooling? Do you need to wait for a child to go to college?
Does your significant other want to do this?
