I sometimes find myself thinking this too then challenge myself to find a low hanging fruit in an area I’m somewhat familiar with and draw a blank (usually).

Low hanging fruit is somewhat the opposite of sour grapes - I don’t want these grapes because they were probably sour versus so what if he got those sweet grapes - they were hanging low!

Maybe connecting “low hanging fruit” to “sour grapes” is “low hanging fruit” to some but it took a serious mental leap for me.
