Flint and Vindictive

Flint :

This word came up when I was talking to my friend and he mentioned about president Obama using this in a sentence " something to do with bringing flint measures to streamline the economy".
A flint is a very hard stone and it produces spark when struck with steel. A search on google brought me this picture which shows how flint can be use to light fire.

Vindictive:
This word came up when Kaira was speaking. She fumbled with this word and caught her using it wrongly and corrected herself. The word vindictive means disposed to seek revenge. Example "a vindictive man will look for occasions for resentment". So being vindictive is not a nice thing as you are subjecting yourself to negative emotions.
