I have been at this for over 11 years now... crazy... can't believe I've been lifting that long. All in all its a great learning process. I just wish I had known then what I know now...
In the last 7 years I've spent 2.5 years as a bobsledder/sprinter at the university level. More recently I've spent around 3.5 years as a male entertainer. My stripping career is over now, but I will be competing in my first bodybuilding comp next year. Based on my recent experience you could say that I have trained solely for vanity in the past few years of my life...
Stripping is an extremely seductive job... man, I still remember my first show, my first year, and the summer that I "peaked"... It was something else! The money, the adulation from the girls, the social/sexual confidence/swagger. I remember the feeling of just walking down the street in my tank top and having everyone, guys and girls stare... its kinda like being a mini-rockstar, except girls wanna screw you cuz you're hot, not cuz you're musically talented and famous!
I have tons of stories from my dancing career, and I'm glad I got to experience it. I made tens of thousands of dollars for basically taking my clothes off, entertaining girls and partying with em... that's a pretty damn sweet. I'll never have another job in my lifetime where I made that kinda money, and simultaneously had that much fun coupled w/ that little stress.
There was a very strong/pressure to look GREAT... I'm talking at the kinds of guys that make girls STARE. You're basically getting paid 200-250 + tips for 15-20 min by the females who book you, so why would they pay for an average looking dude off the street?

I'm Trey Stylz on that site. Despite the pressure to look great, I didn't train particularly for aesthetics. I was younger, so it was easy to stay lean especially with a little bit of anabolic support, and also I was dancing part time to pay for university, so I didn't take it as seriously as I probably should have. I basically tried to be as strong as I could and still stay <10% bodyfat (basically have a 6 pack all the time). In retrospect I wish I had taken aesthetics more seriously, after all that was what was putting food on my table... not how much I was powercleaning.
I have trained heavy and explosive pretty much for 6+ years prior to changing up my current training modality. I found that as I got older I was getting injured more and more. My wrists hurt from having 200+ fall onto them consistently, knees were sore and my shoulders suck.
I felt that making the jump to competitive bodybuilding would take my body to the next level as bodybuilders are fantastic at designing diet/supplementation regimens. I believe diet is 75% of fitness. In addition my genetics are more suited for bodybuilding rather than power or olympic lifting, as I naturally have a wide clavicle structure, I'm not too tall (5'8"), and have some muscle maturity with the years that I've put in. My joints are also a lot happier since my switch over. Overall I'm glad I made the switch.
I don't think I could ever give up lifting... as long as I can physically do it, I wont' stop. It keeps me sane. I love the bodybuilding lifestyle. Eating tons of boring ass food that other people hate, consistently training hard and smart and growing... Getting into elite shape is very difficult... In my experience things are really worth it always tend to be hard... Its a never ending challenge and goes hand in hand w/ one of my core principles of constant self improvement. I also think I'll need something bigger, a goal or an endpoint, to train/prepare for... otherwise I just don't have motivation.
There's a form of sick pleasure in the discipline, austerity, and intensity that the iron brings. I can't explain it but there's something intrinsically pleasurable about lifting a piece of heavy metal for no good reason.
Roiku, as Jitter said, you have a TON of unrealized potential ahead of you... you're 5'9" - 140, just starting your lifting career. To give you an idea I comfortably powerclean what you deadlift. I weigh around 50 lbs more than you and I'm guessing I have way more training experience. Although crossfit will help with your conditioning, if you are looking to get bigger and stronger, it should only be a small part of your overall regimen.
