After taking all of this to get a third place $100 trophy when you paid $200 dollar entry fee. All for the admiration of the clueless who think you actually looked that jacked without the assist.
The list is longer than that.
Most bodybuilders i know do it for personal achievement. The trophy means little to them. Sure there are egotistical people who do it for attention, but all sports have that.
To be fair, i used to race my Corvette in amateur racing leagues all over the country. I'd spend $10-15k a year easily just to have a chance to race for $1500 and a set of racing slicks at the final race of the year. We all put our money, health and lifestyle on the line to do what makes us happy, no matter how shallow it is. It used to scare my GF and parents to death when i'd race; it's driving on the razors edge 100% of the time. 600hp car that weighed 2900 pounds. Sure i have a cage and fire suppression system, but that doesn't always work. Lots of people get trapped in burning cars every year.
I competed in Power lifting for 11 years, have a few dozen plastic trophies. At the time it felt fantastic, but today it's just meh.
That's just the nature of humans. I could have died in a fiery car crash many times, but it never crossed my mind. Going through high speed off camber turns at 120+ MPH with a concrete barrier only 30 feet offset. Seen many bad wrecks, but lucky for me i only spun out a few times and tagged a rubber tire wall in the rain.
Look at all these kids that train their entire life to try and become a pro athlete; baseball, football, basketball. Their parents spend tens of thousands of dollars a year. Are they doing it for their child's chance at becoming wealthy or personal achievement? My best friend spends 20k a YEAR on batting/fielding lessons for his teenage boy. He's a great player, but i doubt he will go pro.
