@BlindGroup: I really recommend it, going back to 9x9 or 13x13 at times is challenging and forces you to make the most out of every move. I like it. It's also less time consuming. If you have only 30 minutes to play, mostly I'd rather have 3 9x9 games than half a 19x19 one

Depends, of course.
Anyway, success is a very subjective thing. Were I to measure my success by my ranking alone, the past month has been "uneventful". After a rather amazing rise to 10 kyu from January to July, things were bound to slow down. But combined with my new "outlook" on Go, meaning no longer obsessively studying for hours a day, it was certain to slow down A LOT.
Yet I feel I've been very successful since my "2nd" career in Go. Only playing when you feel like it means you enjoy every game.
Not caring about your rank means you explore, experiment, open up with moves you ordinarily wouldn't do, aren't afraid to accept handicap matches...
And almost contrary to that is that I've finally managed to leave DDK level behind me. This week I've won a 4H stone match against a 15 kyu, a 2 stone match against a 12 kyu and an even game against a 10 kyu. All in which I was mostly blitzing, only in the first one was my opponent blitzing, too. I feel fairly confident I'd win most of my matches against a 10 kyu in an even match. Of course, I could be mistaken, in which case it'll become obvious soon enough.
Either way, I now have 3 accounts on OGS and they are 8.1 kyu, 8.4 kyu and 9.0 kyu, so I think that says something. Also note that I just said I don't care about rank and yet I list 3 rankings here

However, I use rank as an estimator of strength and see if there is improvement or not. In this case, I see that there has been improvement and I have officially surpassed the DDK-SDK mark on OGS. A small celebration is in order.
Besides that, here's what I need to be attentive about:
- I play a lot of blitz games right now. It's a fun activity in the evening to play a Go game in about half an hour.
(contradicting my opening statement in this post) The danger, however, is that it'd become my standard. I'll take note of that and "force" myself to play real/non-blitz games too. Also because direction of play etc are my strong suits. Tactical playing (requires reading & time) is my weakness. So blitzing doesn't help that a lot.
- L&D with throw-ins. I need to try to kill more with throw-ins and be weary of my opponent throwing in more. I almost never take it into account and it gets me killed often.
That's it for today. I've had a good weekend with plenty of Go games, on different dimensions. I lost against a 4 kyu in a tight battle, lost heavily against a 6 kyu twice, both times creating a dragon for myself after non-sente plays that my opponent left unanswered. (learning opportunity there), won many games, too. Against DDKs, also a 9x9 game against an 8kyu, which I consider a huge victory for me, with my weak tactical skills.
I'm learning all about sente these days. Thanks to dwyrin and his basic series, I'm making healthy decisions during my games.

happy Go learning!
