Persuasive
Thanks everyone - with this and the Twitter replies so far, I have 44 different words! Thats an amazing response. I have time to be adding more in between now and the end of April so if anyone want to contribute, please do so.
I was going to put these on a slide - I may need more than 1 otherwise the font is going to be very small 
Its really interesting for me in that these replies support the subject I am talking about in May. I always doubt myself - so having responses that back up my thinking really helps. At least I can back up with evidence.
pachydermatous - making up 20 chars
Persevering
Meticulous
Diplomat
Determined
Sometimes, a defectās fate depends on how determined the tester is. Especially when developers are eager to identify the problems as āsystem behaviorā without any solid proof.
Very cool, @jfs17uk! As long as weāre making up words:
Collaboversator
Making up ? how very dare you 
You need to be ācustomer focusedā.
Saw this on a slide in a picture tweeted from TestBash Netherlands (thanks @maaret):
Catalyst
As a Tester, I want to help transform words into shared understanding, designs into testable products, activity into value.
Not really a skill, more of an attribute or characteristic: courage.
Canāt belive it was not listed yet: empathetic!
hmmmm well maybe telepathic 
Now now rules are rules
one word
Oh, that would definitely leave me in trouble - I failed Telepathy 101!
I knew you were going to say that!
Passionate
I see too many tester that donāt act like testers, they donāt care about learning more about testing, they donāt know what testing is, they show off some very stupid things, they disregard context, they trust too much on ācertificatesā which stops their progress, they follow too much the bad market trends that sell, they donāt think critically about themselves, see testing as a job and not also as a pleasure, they refuse to switch their job because they donāt want to learn something else - and testing is āeasyā to do, they accept any requests without questioning them, they are stuck in documenting a lot, they do just automation checks all day - rarely testing or learning about anything, they are defined by the requirements others have from them.
With passion I think you can learn to be good, learn to have your own opinion, to have a spine to stand for your ideas, to challenge others, you can have the words and gather courage to say people are wrong, you can be efficient, you can work on your weaknesses, you can become someone respected.
Thank you all. I have a great long list to use in my talk and my slides are now done (well unless i tweak a little here or there!). The talk is going to be recorded so Iāll share where that is if people are interested.
