Train of Thought

Sort a train of words according with the following rules:
* The next word could have one letter added, removed or changed.
* Or it could be an anagram.
* It could also be a synonym or antonym.
* The two words could be logically related (like 'arm' and 'hand', 'tea' and 'cup').
* The words can be found in a common saying or other cultural references ('stick' and 'stones', or 'brave' and 'world').
Hints are available if you are stuck, and the assist mode can be activate for further help, which only accepts correct guesses.
