Sometimes you have to find the simplest / smallest change you're able to sustain. I've heard so many times how #eBikes are life-changing because they put actual destinations within reach and you don't have to worry about overexerting yourself to make it home. 5 minutes is easily 1 mile on an e-bike, allowing errands or school dropoff to be done with only moderate exertion and often more quickly than via driving. The "15 minute neighborhood" becomes a 1.5 mile radius.
