You betcha! I have never been so busy!
A friend started a business mid 80’s, I took a pass on being a partner, but did work for him.
He started every morning at O-dark thirty AM and attempted to leave at 5 PM. Many years no vacation. In fact a few years I took home more than he did.
They did 36M last year, so he’s doing ok now.
He retired last year to build a house! He’s the general contractor and does all the scutt work. Never stops!
And not only does such joy continue until the end of this life, but it continues with even greater passion in the life to come!
