I am in my early 30's and currently do not have kids or pets to hold me back, only a great wife who will be coming with me. Please donate and there might be a good potato salad recipe in it for you.
then you have no excuse to NOT follow your dream. If the job is as bad as you relate, then you have nothing to lose, and a lot to gain. You are still young enough to recover from any failure that may occur, yet old enough to enjoy the adventure immensely.
You could lose your job in the am, and you will be subject to the whims of others to recover. It would be best to do things on your terms, so call the wife and tell her she has a week to find a boat suitable to you both and with in your budget.
Then go visit the top 3 each of you have found. Pay attention to the wife, her comments and body language in particular.
You will find out whether this is something you both want to do. Buy the one she loves, and you like, get a survey and move aboard. OR walk away and return to your life. At least you looked at it seriously and decided to walk.
What ever you do, don't put off the choice, in hopes of the job or life or paycheck getting better. The times have changed and these things are subject to change badly, go away at any time. Seldom do they stay the same.
Best of luck and enjoy the adventure.
