I’m a pistachio fan. When you eat them, I recommend you have two bowls – one for the unshelled nuts, and a second one for the non-useful shells. You’ll be able to tell for sure which is which – the useful from the discards. That way you will be able to put your hand into the big bowl and know for sure you will get a good one.
That approach works wonderfully with pistachios, as well as ideas. Some ideas are good, applicable and fit well with our current need. Other ideas may be discards your group decided weren’t useful.
Sometimes the best ideas come out of the idea junk pile. You may have discarded some ideas and put them into the “that will never work” pile. Perhaps later that idea will work wonderfully well because the timing has changed.
Be open to cast-offs. Some might be the key to the next obstacle in the way.
