I've heard of SMART, yes, but I'm not much of a fan as we heard it none stop in school in business class.
And when I went to one uni adviser about being stuck on studying, etc that's all he was able to come up with. I can see the logic and usefulness in it. But, yes, it wears a little thin for me although you've fleshed it out a little more than uni guy was able to as he was in generic appointment mode.
I'm getting used to a new routine now, invariably up at 6am, home after 7pm...shower, eat, potter about on the PC and that's about it on those days. Was very, very tired last week - am hoping this won't continue, as it meant I was also irritable - think getting my in gear a bit will help in some respects.
I have thought about running a marathon, so regular exercise would be important for that. Or a half marathon, or joining a gym. But, for me, staying in too much can be cabin fever and things can get stressy when I don't engage in things and remain too isolated. I'm bad at hobbies, need to restart some and pursue some new ones. It'll need to be small steps.
Food for thought, though, thanks.
