Hey Emilliano!
That's fantastic - a man of action. I like it

I think the only thing you need to really succeed is to keep doing it. Two women a day is great, especially for a start, so don't stop. At least keep it up untill summer.
Also, what kind of "material" will you use?
If it's scary at first, simply ask for the time or for directions. From there you can transition into some random conversation, or simply move on.
One thing that's important is that you don't push yourself too hard. Do it in your own tempo, but don't stop improving, either. Slow is the way to go, both literally and figuratively

As I said before, I'll say it again: the most important thing for improvement is consistency. Just give it some time, and don't be knocked out by small mistakes. Learn from your mistakes, and take pride in the fact that you're conqueering (or at least befriending) your fear.
I look forward to seeing your progress, it seems like you're a good guy with good intentions, so all the best of luck from here!
