Your horizon is just today's problems with a sunset filter.

This quote suggests that while horizons symbolise new beginnings and opportunities, they are often just current issues presented in a more appealing light. The sunset filter is a metaphor for how we dress up ongoing challenges to make them seem refreshing or significant.

The humour lies in the idea that despite the picturesque appearance of a horizon, the underlying reality remains unchanged. It serves as a reminder that no matter how much we romanticise the future, it is often just a continuation of present difficulties with a superficial makeover.
