chase rainbows
Meaning
To pursue an unrealistic or unattainable dream or goal, often wasting time or effort on something unlikely to happen.
Origin
Based on the idea that a rainbow recedes as you approach it, so trying to reach it is futile; it also echoes folklore about a “pot of gold” at a rainbow’s end.
Notes
Usually mildly critical: implies the goal is unrealistic and time/effort may be wasted. Common in advice or warnings; can be softened or overturned in contexts where the dream succeeds.
