Liky, I see by your stats page that you play no blitz. This is the purist approach recommended by Drahacikfm and it seems to have paid off for him and also for boromir, for example. Boromir's standard rating graph reminds me of a monk climbing a mountain to make a pilgrimage at a shrine, or the tortoise in the Aesop's Fable about the Tortoise and the Hare (with the moral ("Slow and steady wins the race").
Then there are users like you and me who can't maintain the ascent. I had one night playing standard where an especially annoying problem made me go "I give up, you stupid mountain!" Then more recently a narrow spike in the graph when I said "Okay, top of the mountain or bust!" and got "busted" a few problems later. :-)
If standard is making you feel frustrated the same way, I strenuously vociferously recommend you switch over to blitz at least for a while. You'll probably find it's a lot more fun and rather than permanently ruining your patience for standard play, it will "burn-in the ROM" for a number of standard mating & tactics patterns you have to know anyway to play good standard in the first place.
I take the metaphor from Rashid Ziyatdinov's mysteriously laconic book "GM-RAM". Chess Tempo is like a hyperaccelerated computer version of that book. After several months on the site I have acquired many new "chess neurons", one for each tactical pattern. There's a neuron that notices the possibility of an "epaulet mate", a neuron for a queen forking the enemy king and rook (or merely moving to a square where it threatens to), and a neuron for the pattern Kh8/Pg7/Ph6 and we have a bishop on the a1-h8 diagonal and we play Qxh6+ and Qxg7#. Of course for each of those neurons you need a "companion neuron" that checks whether there might be a wrench in the works, e.g. at
http://chesstempo.com/chess-problems/45825the pawn we want to take is guarded! ("I'm up to your tricks now, CT! -- Oops, moved too fast!")
Now, those of us who are "harebrained" enough to play blitz can't necessarily expect any better or quicker results than at standard. You might not see a climb in your graph at blitz either. But I guarantee that you will be rewarded in the long run with the feeling of pride at having actually learned something, regardless of rating points. :-)
