I don't have any clever suggestions but I'm interested in what you come up with. I love to hear how creative people get so that they can commute. For example, leave the bike at daycare, drive part way & bike the rest, bike to work & drive home & next day drive to work & bike home, and so on.
I have heard people say that they do less because they bike. They don't feel like it's a sacrifice, more that they have a slower pace of life and don't do so many movies or activities or whatever. I've mostly heard that from car free families. I don't feel that way but I'm not 100% car free. Even if I were, my family is not, and I don't think I would do less, I'd just bike more (which wouldn't be a bad thing). But if the whole family were car free, yeah, I bet we'd do a little less. And I don't think we'd mind. At least I wouldn't.
But that's just the people who have chosen to do it that way. Maybe the reason you never hear someone bemoan the loss of their activities is because if they really mind they are not going to give up their car. That doesn't make either choice right or wrong. It wouldn't make sense to give up something you really love to do anymore than it would make sense for you to give up delivering the Food Bank food.
Keep sneaking in as much commuting as you can, either to & from work or also consider running errands by bike once in a while. Maybe if you have extra time on a Food Bank delivery day, hitch up your trailer and do the delivery by bike! Go for a ride at lunch. If you "only" commute 1 or 2 days a week, well, that's 1 or 2 days more than most people.
