A common mistake people often make is refusing to try something again that didn't work before.
On the surface trying something again that failed in the past may seem counterintuitive. The reality, however, is that outcomes are driven by many things: circumstances, the market, your audience, your company's infrastructure, and your mindset, just to name a few. If any of those things have changed over time, then something that didn't work for you five or ten years ago may work now.
Proceed with wisdom, obviously, but don't be afraid to proceed.
