How is your weight/eating habbits?
I recently turned 40, work 45-50 hours per week on average, have a wife that works 3 days/wk, and a little 4 month old. A couple months ago I found myself feeling exhausted and "dead". I let myself get up over 210 lbs (I'm normally in the 185-190 range). I was also going through a 15 pack of soda every 4-5 days (I was using it to get through 12-15 hour work days). About 6 weeks ago I quit the soda (crap was that hard) and do 25 minute video work outs 4-5x per week. I've lost about 5 lbs so far, but I have SOOOOO much more energy than I did a couple months ago. I'm sleeping more regularly too. I'm already eating less because I'm just not as hungry. 2 of the guys working out in the videos are 45+.
You don't have to reply with your situation, but something to think about. I know it takes time, but we always find a way to make time for the things we think are the most imporatant. Replace a TV show with workout time
The other thing I've had to accept is I can't do it all anymore, nor anywhere near as fast as I used to be able to. I actually haven't done any "car stuff" in almost 2 years because I started a massive shop build. It's already $ enough, and I don't have the $ to pay someone to do it, so I've pretty much built this entire 28x52 shop myself aside from dirt/concrete, and wiring. The goal was to have it done in 12-15 months, well, 18 months in and I'm far from finished. But it will get done.
The other thing is to not have "too many" projects. I have a running/driving 67 C10 and 65 Mustang and a 68 Firbird non running project car. I don't know how/why some people have 15 project vehicles and maybe only a couple (or none) that run. My dad is actually one of "those people" and as well as I know him, he'll drag something else home and push whatever he was working on outside nowhere near finished, he's still doing this at 58. I've never understood.
