hard time getting motivated

Same situation here as some, multiple back surguries and still several herniated discs. Motorcycle wreck back in 2001 and I'm 44 now. A lot of times " not today" and sometimes force my self to piddle on it even if just an hour. Thankfully I have some outstanding friends that will come by and help me move stuff around,but I have to wait. I try and set a small weekly goal and stick to it. Eventually you'll get it done.
