That's it, that's what it comes down to. I can only recommend that you figure out your "WHY" again, that's the source of motivation. I realized all the years my only answer to my WHY was "Well, it's gonna be nice once I made it". That's not enough, that doesn't get one out of bed, that doesn't keep one from wasting time during the day. Everybody has their own why, maybe you do it for your family, maybe you made a promise, whatever it is, find it out.
The WHY never changes, you stick to it, that's how you get constant motivation.

I've slept 8hrs since I started this thread, haven't wasted an hour and man it feels good!
