where does motivation/work ethic come from?

<p>My two kids are complete opposites. S1, self motivated, hard worker, driven to achieve his goals…school work came easily for him since day one.</p>

<p>S2 , happy (or should I say relieved?) from day one to get by with the minimum required, never cared about his grades compared to others, only worked as much as he did because he knew he would be in trouble with DH and me (which he was frequently) if he did not. School work never came easily for him as it did S1.</p>

<p>They are 3 years apart. Same parents, same household expectations, two different kids.
Nothing we could say or do changed S2’s academic adventures.</p>
