How to go the longest.
First grow one soy farm, and plant one cattle farm.
Next go to the feedhouse and check all the cows.
then, go to the store and open one stand and one lane (one of where you buy one of where you make)
After the cows grow to adults put more cows in, when the dirt gets dirty, play soy over that area, then replace one soy area with cows repeat after all four seasons.
*TIPS*
1. always check your cows make sure none are sick or mad when there made into meat.
2. when sales pick up open another stand and maker.
3. remember to check your cash before you spend.
4. remember to go to HQ and make your name known.
