Today I reached one million SPI points, I'm only a third away from diamond ears. Some games are extremely frustrating at times, but little by little I'm getting better, although I still can't get past level 8 in some games, and I've reached high levels in others. I think it's all a matter of persistence and patience. I don't have much time, so I usually just do the 5 exercises of the daily training, but some days, like today, I did some extras to get to 1M.
I'm going to keep going, but with the main goal of improving far beyond scoring points!
