Look at what you can do to make things better rather than what is going wrong. You'll be amazed at how much better your workouts and nutrition can and will be when you take a slightly more positive approach.
Take an hour a day, a week, whatever it takes, to figure out exactly what kind of lifestyle you want to live. Eat and train accordingly...
...it's not just WHAT you eat; it's how well you fuel YOUR LIFE that leads to complete success.
If it's hard, difficult, challenging, and/or intimidating, KEEP GOING.
If it hurts, STOP.
Accept that you know very little about most things...
...if you plan to make a change, learn how to do so, properly.
...if you are going to judge, take a look at what you are doing.
...if you are going to make a claim, find out if it's right.
Take plenty of rest days. You will not become fat and out of shape; you will get in better shape and prevent injuries. Recover with the same intensity with which you train.
Get to know your kitchen. Seriously, I know more people who can talk their way around local restaurants better than their own kitchen, it's pretty sad.
Earlier today I was unfortunate enough to get involved in a pretty humorous argument my college guys were having as they warmed up before class (this obviously inspired my first point above...). While I immediately realized it was just not going to end with any sort of progress made, it got me thinking about how much most people do not know about health and fitness. As a fitness professional, hanging out with other fitness fanatics like myself, and reading article upon article about it all, I sometimes forget that the world I live in is still a pretty limited world in terms of its serious population. Shoot, even people who claim to be a part of this world have no idea what's going on (how many "trainers" have you seen who are over weight, relying on rehabilitation machines for their workouts, and eating like complete crap?! I have seen TONS!). What I have found over and over again is that peoples lack of knowledge in what is truly good for them is a slippery slope to injury, sickness, limited or stalled fitness gains, and an overall negative and lethargic lifestyle.
If your energy sucks, if you sleep like crap, if you're overweight, if your productivity is down, if you're in a bad mood all the time, feeling frustrated, depressed, angry and so on, perhaps you need to make a change. And as stated above, REAL change will be hard to come buy if you are not educated in what you need to do. Read a book, read an article, talk to a professional, take a class, watch a documentary, try things out.
Never Stop, GET FIT.
