This is another tough one. I think the answer could be different for everyone. A bold choice for one might be a safe choice for another.
To live boldly would mean to make the choices you want to make.
To do what’s best for you.
To live the life you want to live.
To love who you love.
To worship the way you want.
To not worship if that’s your choice.
To be your true self
To do all of this without worry about what anyone thinks.
That is living boldly.
