For some people they find that keeping / starting seeds in pots too onerous, another strategy is to find an out of the way place in your yard and sew the seeds in those areas. That was my plan when i was a kid as I couldn't afford buying pots or potting mix with no salary! So, I would find small areas behind clumps of irises and daylilies and plant either a row or just scatter the seeds in that area.When I was planting, I would map out these areas in my notebook so I wouldn't disturb them by mistake. They might not germinate as well as they would in a pot but you get seedlings to come up and they survive with even quite a bit of neglect. I would transplant these seedlings a bit later, letting them develop more sizable roots, so that they aren't quite as vulnerable to the environment.
I like my new system better as I get better germination, more consistent plants and much better growth. I can evaluate them in one season and re-use the bed for a new crop of seedlings.
