#### Abstract

Summary: On a separable, infinite dimensional Banach space $X$, a bounded linear operator $T:X \rightarrow X$ is said to be \textit{hypercyclic} if there exists a vector $x$ in $X$ such that its orbit $\mathrm{Orb}(T,x)=\{x, Tx, T^2x, \ldots\}$ is dense in $X$. However, for a unilateral weighted backward shift or a bilateral weighted shift $T$ to be hypercyclic, we show that it suffices to merely require the operator to have an orbit $\mathrm{Orb}(T,x)$ with a non-zero limit point.
