Well that is a personal preference, and yes the simulator is accurate and actually very nice made. The thing is you turn on your computer and play the game, behind the scenes there one's and zero's running back and forth. In a real life it ain't one's and zero's it is your alarm clock that goes of in a very cold morning and you have to get out of bed and in fifteen minutes you are milking cows if you like it or not.
Lucky me, my father doesn't own a farm so I only have to watch and really experience. Because of my experience I'm not the kinda guy that wakes up to early in a cold morning.
Why am I writing this, well the point I want to make is don't make up who you want to be by playing a simulator.
Go and work at a farm (if you didn't do already) and then see if you still want to be a farmer.
Hard work, and the pay is low (financial speaking)
