I'm six months pregnant and horribly overwhelmed, so I've enlisted the help of a local gardener to tackle the more pernicious intruders (such as green alkanet, which leaves my ankles feeling bitten whenever I hang out the washing, and some of the many robinia saplings that have appeared from the neighbour's great big, beautiful tree) while leaving the good stuff behind. Then, in the patches that open up, I'll be sowing green manure.
