Derech HaMelech
I find myself agreeing with you often. There is no Inyan to cause oneself distress. We have a Torah which tells us how to live. Hashem doesn’t want us to make up our own commandments and devise imaginative ways to serve him.
“I stoppped dreaming about the sculptures I’d make, or the tapestries I’d embroider.”
Im an FFB and I never heard of the commandment “Thou shalt not make tapestries or sculptures” yes there are certain sculptures which may be a halachic problem, so find out which ones are permissible.
And what’s this business of not riding in the front seat? Being a BT doesn’t mean you should be an extremist. Hashem wants normal healthy Jews who keep the Shulchon Aruch. Don’t make up crazy chumros that will make you miserable.
