Took me a long long long time to realise I could even discard plane orders so I highly recommend discarding what you can?t do. Just keep crafting and planting crops to build your do and more things will open over time.
As your barn is also small, don?t hoard things you don?t need. If you haven?t seen it in your craft buildings, get rid of it so it?s not taking space. If you see a craft takes a long time to craft like maple bread for example, if you see it buy it as it will save you 4hrs and a slot in your building.
