put on ice - postponed. Or killed. in the doldrums - depressed or unhappy. You can also say 'down in the dumps' or 'feeling blue'. like greased lightning - fast. Sometimes as a negative meaning. in a fog - confused a windfall - ANY sort of unexpected good luck, usually involving something tangible like money or a promotion. put a wind up - [[put the wind up]] - too feel a little worried. Hardly ever used nowadays. blue skies - while it does mean 'optimistic', this isn't entirely true. When you say "And it's all blue skies from here," it means that you can't see any problems or worries in the future (usually about a specific situation) because whatever problem you had HAS BEEN RESOLVED. So it's not exactly 'I'm feeling optimistic about something', it's more 'And now the problem is fixed, everything will be fine'. You can also say "And from here on it's clear sailing" ('smooth and easy', 'trouble free', 'easy', without difficulty') - always used with some form of 'to be'. Hope this helps. :)
