Everybody comes in with a certain goal. Some are performance, some are aesthetic. Even athletes have aesthetic goals, but first and foremost, they have performance goals, and those need to be addressed. They have weaknesses that need to be shored up. You have to manage expectations sometimes.
Hydration is everything. Think of this: your muscles are 70-plus percent water - how are you not drinking water during a workout? I get the whole, 'Let's challenge ourselves; let's do that prison, tough guy thing,' but at the end of the day, you're underperforming.
I try to do the right thing. If you do what you know is right, and you're a good person, you might not win short-term all the time, and financial gains might not be there all the time, but ultimately, you can be pretty happy, and you can do some pretty good things in the world. Keep a positive outlook.
You need to lift weights and do more resistance training. Get more sleep. I'm the first one who's guilty of not doing that, but I work on it, and I'm aware of it. And drink more water. Drink Propel. You have to hydrate. You simply can't perform at the level you could perform at if you're dehydrated. Period.
