If there's anything I've learned in my decades of being an athlete (yes decades, I found my gymnastics report card from when I was 5 the other day), it's that the only way to succeed is to take full responsibility for yourself. Have I always done this? Nope. But I'm getting much better at it. The big reason for failure? Excuses. Here are two kinds that are a sure fire way to failure (both of which I've been guilty of).
1) Excuses in training. Dear god these drive me crazy. Now I'm pretty immune to complaining, because I do complain from time to time, but as long as you get the work done, I don't care. Complaining is different from excuses. Complaining sounds like this "UGH I DON'T WANT TO DO THIS!" which is what I say before every squat set over 3 reps. Excuses sound like this: "I didn't get enough sleep last night and that's why I failed my last front squat set!" or if you're a weightlifter/CrossFitter "My hands hurt so I can't do my snatches!" I think part of this is we expect to be and look awesome every day in training. Training is just that, it's just getting us ready for something bigger. It's not a competition. Who cares why you didn't hit that snatch or couldn't go faster on your row? "My legs are tired from moving into my new apartment this weekend!".....Nope still don't care, just do the work. And if you can't do the work, quietly adjust the weight/reps, and move on.
Even if you don't vocalize your excuses, they're toxic. You're protecting yourself from failure, but in doing so, you don't move forward either. Failure is the best thing that could happen to you. It makes you better. It teaches you things. Stop trying to protect yourself mentally from failure. I'm learning there's a life beyond 6 months from now and I have my whole life to fail and figure things out. As I'm sitting at my desk in a leg brace, still rehabbing my fairly fresh ACL, I can tell you I'm pretty familiar with failure. We're pretty much bffs. My training sessions are full of failures (failed lifts, failing to squat using both legs equally, failing to dip in my push presses without compensating by pushing my hips back) but they all teach me things. Yesterday, I finally got fed up catching my lifts to my right, so I spent about 30-45 minutes doing single leg exercises on my left leg on top of my programmed lifts, and I plan on doing those a lot more. My failures got me to take action to become a better lifter, and down the road I'll appreciate that.
2) Excuses why you'll never succeed no matter what. Guilty of this one big time. I'm a 75kg weightlifter. I'll probably always struggle to make weight. I also have the longest femurs known to man. Now I could keep that in the back of my mind every time I struggle with a squat set (try every set?), or I could decide that I just need to work harder on my core strength to MAKE UP for my long femurs. Go the extra mile. Also realize that in your weaknesses there are also strengths. I'm 5'10''. That's pretty tall for a female weightlifter. I also have an insane pull because of it. I'm going to put my strength with my weakness and use both to my advantage.
Putting limitations on ourselves prevent us from succeeding, whether we realize it or not. Especially when it comes to nutrition, mostly because society has made dieting this big hit or miss mystery and most people don't know what they're talking about (just cut carbs!). I know a bunch of people that come to me saying "Nothing works! I'll never lose weight!" I even read an article an extremely overweight woman wrote about her struggles in her marriage dealing with her weight, did her husband not believe the research out there that diets don't work? Wait, what???? The right diets work. Just not whatever you did.
I got a big slap in the face when I contacted a nutritionist to set up my macros the first time I started IIFYM. I told her "I'm eating 1900 calories a day (just calorie counting, no macro counting) and I'm gaining weight! Wtf! She came back with a big long list of reasons why I possibly wasn't losing weight. Hormones, salt intake, supplements I wasn't tracking, creatine. Cool, all things that weren't really my fault. She finally weaseled out of me the fact that my cheat meals on Saturdays with Greg were in fact the biggest binge eating sessions in the history of binge eating (even when she asked me what I ate, I downplayed it, left out certain foods, or summarized one of the more conservative binge eating sessions we'd had). Greg called them cheat meals. I now call them binges. They weren't healthy. The problem was, I was perfect every other day of the week, then on Saturday, after starving myself for 6 days, I'd eat everything in sight and put that entire calorie deficit back in my body and then some, and call it a cheat meal. My body held onto every single little calorie. And I gained weight. Crazy huh? It was entirely my own fault. I wanted to ignore the fact that I had anything to do with my weight loss frustrations. I put my cheat meals in a box and pretended they didn't exist, then cursed the gods because I was working hard the rest of the time and not losing weight (that's not how it works, that's not how any of this works). Facing myself head on has made the process much easier. And now on the weekends when Greg wants to go crazy with the food, I remember what my nutritionist told me, and that the laws of physics (and thermodynamics? that "energy" I just ate doesn't just disappear into thin air, it has to go somewhere) don't go out the window for 2 hours on Saturday just because I wanted a pint of Ben and Jerry's with my pizza and chips and salsa and cheese sticks.
