Constructing an adapted process for a given stopping time

Question

Given a filtration $(\mathcal{F}_n)_{n\geq 0}$ and a stopping time $T$, show that there exists an adapted process $(X_n)_{n\geq 0}$ such that $$T=\inf \{n \geq 0 : X_n >0\}$$

I'm really lost where to even begin here, any help would be appreciated.
