  We consider the BVP $-y" + qy = \lambda y$ with $y(0)=y(1)=0$. The inverse
spectral problems asks one to recover $q$ from spectral information. In this
paper, we present a very simple method to recover a potential by sampling one
eigenfunction. The spectral asymptotics imply that for larger modes, more and
more information is lost due to imprecise measurements (i.e. relative errors
\textit{increases}) and so it is advantageous to use data from lower modes. Our
method also allows us to recover "any" potential from \textit{one} boundary
condition.
