make them do chores when young so they know what it is like to work, and learn how to work. Do it with them and they will enjoy it more. Give them something at say 14 years old ,ex Calf, sheep, 1 acres,. whatever you farm just part of it. it is a lot easier to have an interest in farming when you own something of it.
NUMBER ONE DON"T .....make him do dishes till 16 and leaves home while his other brothers were givin a cow at 13 and are out making money and the third Gets nothing. Made me very bitter
