well
Marivs, the first part of your post simply don`t make any sense. Again, you just don`t understand the concept of it.
And in one way it's even good that you try to play your way from time to time (not often!!!) because mistakes that cost you money are the best experience you can get in poker. And so you get more experienced and in time you are able to evolve in to a solid player, unless you are stuborn and just won't learn from your own mistakes (and mistakes from others), than maybe poker just isn't the thing for you.
I see it a little bit differently) In my opinion, one should start with 100% basic SSS , simply because it is the fastest and the most effective way to climb low limits. Meanwhile, one should work on his multi tabling skills, leaks finding and fixing and studying equity and pot equity. Then, when you reach higher limits, you can use statistics and your accumulated knowledge to deviate from basic strategy and make equity adjusted moves.
Pokerstrategy offers great opportunities to study the game. I recommend you to take advantage of it.
