Three quotes including the word "small". That is no "small" victory. That is one big hairy can't-fit-in-your-living-room victory! It's exciting, it shows you're achieving something, it shows that you are totally capable of learning Welsh, of understanding Welsh.
Now watch out, because you'll get used to that level of victory, and come to believe that to really be moving on your need bigger and bigger victories, and then when they don't happen, you'll feel like you're not moving on (There's a term for it - hedonistic adaptation, possibly - where you just get used to good things and think they are normal).
But if you have one "small" victory like this every day, relentlessly - learn a new word, become more comfortable in one sentence or pattern, understand a new word, or from a different speaker / accent - then you will become a comfortable and confident speaker very quickly indeed.
By the way, the fact that you are excited enough to want to share what you thought was a small victory on a public forum also makes me think that you are very much on your way to being a Welsh speaker, lucyann - I'm really excited for you!
