Was going downhill, suddenly going uphill!

I was constantly going downhill in rating but now I have won almost 10 games in a row (except one where I clicked wrong). I do not understand why I suddenly started to win. I there a strategical shift which I should focus on which made me win? Can you please quickly review few of my previous games? And maybe briefly compare it a bit with ones that 1re more than 10 games ago?

Or is it just plain luck? I am not cheating that is I am sure of :D
thanks in advance!
