All right, since I had to work today, I wasn't able to do anything about asking for letter of invite.
But I say Day 1 is fruitful - I didn't expect I'd be getting that much from my last pay. With the current airline rate, I think I have enough for the air fare.
But, I still have to save for my food and accommodation there.
And more importantly, still, I got no letter of invite. But at least I have the seed money so, more income, a letter, and I'm set.
Day 2: prepare the package to send - and write with all my heart.
