Here are some things you can do to keep in-step with your goals and possibly reduce stress levels.
First understand that despite having worked many years at the same job you may need to rethink what your new career path is. Times are a-changing and that means we may have to.
If you enjoy cooking for others test out on a small scale a homemade recipe that is cost effective to duplicate and see if you can realistically handle orders for your goods. You need to factor in the cost, preparation, facility if your home cannot accommodate your new venture and if you plan on asking for volunteers, such as family and friends and if they are reliable or one-hit wonders.
Maybe you like to write. Find your niche. Mysteries, fiction, hobbies, craft, you name it. Like novels? Think you have what it takes to become a writer or author? Try submitting short stories or poems to a company looking for new writers.
Take the time to practice whatever craft it is you have and see it through. Seek out companies that specialize in the areas of expertize that you want to work in and can offer the greatest yield without compounding start-up costs that you may not have anyway, especially if money it tight.
Write down your goals and time frame so you can at least get your new career started on the right path.
You have a blank canvas on which to write out what you want to do for the rest of your life.
Value what you have to offer and research what it will take to make it happen for you.
Let me know how it goes and I wish you much success!
