<p>The great thing about doing what you like is that you excel naturally...I was too much of a chicken to go for what I really loved, and studying isn't exactly enjoyable...I have to "work" for my grades. And yet, when I take electives in fields that interest me, my grades are usually high, as I enjoy the studying process.</p>
<p>My advice: we live in a VERY competitive world. For that reason, I believe the safest thing is to go for what you're good at and enjoy doing (so that all those hours of work don't become an inferno). The important thing is to have realistic expectations about future employment/salary (e.g., I will not earn a six-figure salary with an English major).</p>
