Ever just get tired?

I have been at this hobby since I was 17 I am now 52, I have restored 70-75 cars in that time. Hemi’s , SIX PAC, light weight Ford. No brand loyalty. In 2013 my 30x50 shop burned I lost ‘68 chevelle, ‘69 SS Chevelle, ‘70 Nova and all tools spare parts.
I build a replacement building 30x40 but my heart is just not in this anymore. I keep doing it because it is all I have.
