A simple compliment goes a really long way - for a guy to just come over and say 'You have great hair' or 'I really like your dress ' and then just smile and walk away. That's a great move because he's sort of putting himself out there by doing that but it won't lead to any embarrassment if the girl isn't interested.
Don't be afraid to give your best to what seemingly are small jobs. Every time you conquer one it makes you that much stronger. If you do the little jobs well the big ones will tend to take care of themselves.
