One of the great stresses in life is leaving an unfulfilling job.
Recently, I had the same realization as you, and I found some wonderful stories of people who took the leap and left their jobs. To date, I don't think I found one story of someone who regretted it.
Continue pursuing your passion and your own business! It's clear you are already happier!!
One suggestion, I noticed some minor grammatical mistakes. Believe me, I'm no stranger to making writing mistakes, but I use Grammarly to find and correct them. Their service is free!! Just something to consider.
Overall, fantastic job encouraging others to find their professional calling. I love the positivity in your story, and I thank you for sharing!
