Willy, I think this can be a really helpful thread!
Problem: Nutrition. You guys are going to hate what I'm going to say, but I definitely screw up in this department. I wax and wane between eating too clean and not eating enough. Yup, there you have it. I hold the reins too tight.
I know I don't get enough dietary variety. Too many years of eating what I know "works" means eating (pretty much) the same old thing over and over again. I've read some of your food descriptions (Hel, Willy, Elaikases) and thought, "gee that sounds so scrumptious," but I'd never dream of eating anything like that myself. Hm.
Yup, I have a very odd relationship with food. (I think it's only fair to mention that on the up side, I have a relatively low bf% and my weight is always somewhere within 2-3 lbs of my ideal.)
Fix: I need to try to cook with an eye for a little more variety. Best solution I can come up with is to make an effort to try one new recipe a week or dig out an old favorite recipe that I haven't made in a long time.
I did that last week when I made Jumbalaya. It was great! Of course, being the way that I am, I'd be perfectly content to eat Jumbalaya four nights in a row. Sigh I'll let you know how this works out.
Sleep: Damn mid-life crisis. I seldom wake-up feeling rested. Not in the last two years. This seems to be getting a little better, but its taking forever.
Fix: I've set a new cut-off time so I'll get ready for bed 1/2 hour earlier, more if I can swing it. I find that if I get in bed with a book I'll usually only last a few minutes before I turn out the light and crash.
Stretching: I do it, but I'm not always 100% on board.
Fix: I'm thinking break it up into 2 shorter sessions instead of one. That way if I miss the evening session I'll still (at least) have done the morning session. Looks good on paper, but will I do it?
Attitude: I'm a little embarrassed to admit that at my age I'm still too hard on myself. I've heard it several times since starting Muay Thai and BJJ, so I know I'm not making this one up. I need to lighten up and have FUN.
Most of my hard/heavy lifting days are behind me. The MA stuff should be a challenge, but it should be fun. So they say. I know I've eased up on myself in MT, but that's only because I'm getting better at it and can actually see my own progress. I'm still pretty clueless in BJJ and I let it bother me way more than a rookie probably should.
Fix: Being a rather intense, serious person, I have no clue how to fix this.
I think those of us who are coming clean should periodically come back to this thread and post our progress. If we're making progress that's great, but if we're not, then maybe we can get some new input?
