You won't learn how to beat $10 mtt's by playing freerolls. Sometimes it costs money to get better at the game.
You can learn a bit playing in freerolls (a bit more in some vs. others)... although these days I don't think there are many (any?) where the general skill level could be considered 'good'.
In the beginning I didn't see myself as a 'good player'. I was new! But within a week of signing up I was finding forums (including this one) and asking members for resources that could help me get better at the game (back then it was books and training sites). So I did both. I read over 50 books my first year playing poker.
In short time I probably did think I was better than I actually was (< this is common for newer &/or novice players). I actually placed 2nd out of close to 1,000 entrants in the very first MTT I played online and yes this gave me a false sense of being better than I actually was. So I lost for the next 2 mos., at around roi -10% for Sng's and for MTT's I just didn't get a good cash again for awhile. But then I focused on SnG's for awhile, reading some good SNG Guides at the time and two books that were about sng's (one was written by the guy who did the CC 30-day course). And then sure enough, I was a winning player at micro stakes SNG's ($5 games). And then I branched out to multi-table sng's and small field Private league games (there were TONS of private leagues then... sometimes on a weekend I could find 25 MTT's to play that had leaderboards, Ca$h-Added prizepools & loads of prizes, across a couple dozen different sites. There were a couple hundred players playing in those tourneys so you'd get very familiar with each player and how they played... so I worked on making adjustments to each type of player and worked at exploiting them to the best of my ability).
So.... I didn't start out seeing myself as a good player BUT I was determined to be a good player (or good enough to win the games I was playing at the time).
Pretty much the only thing I wish I had done differently is >>> I wish I had taken more risk by attempting to move up in buy-ins sooner than I had.
Today my goals are much different with poker... but maybe they'll change again in the near future
