I learnt a new expression yesterday: to "marinate an idea". It has to do with having an idea and then leaving it alone for a while, for all the flavours to infuse.
When there is time - like on lazy summerdays - I find that marinating ideas is a great way of moving forward. Things fall in place. The trick is to be patient enough to leave the ideas alone for a while and just wait for them to become more juicy and tasty, ready to put on the barbecue and dig into.
