  Hadronic interactions are discussed within the context of the constituent
quark model. The "Quark Born Diagram" methodology is outlined, extensive
applications to meson-meson and meson-baryon interactions are discussed, and
general features of these interactions are highlighted. The second half of this
document deals with shortcomings of the quark model approach and methods to
overcome them. These include relativistic kinematics, unitarity, nonlocal
potentials, coupled channel effects, and the chiral nature of the pion.
