Whatever motivates you? Long sweet spot efforts are mentally challenging.
What motivates me is going outside and doing these freestyle and not worrying about hitting exact targets.

Back in 2016 I was new to cycling and just did what I could, was never able to do 3x8-min above threshold but still developed great fatigue resistance and ability to repeatedly go over threshold.
