It seems that you very quickly deviated from your original plans. Maybe you should first earn some amount of real money in order to play simple money games and not freerolls and then start the challenge? As for the analysis of hands, I think it will be interesting only after you show great success in poker 
You have a gross misconception about my 'original plan'. Please take a moment and read before replying it is the second time you get it wrong.
I have never said that I will be only playing freerolls. Freerolls are just a stepping stone to get the initial money so that I can play real cash games since I was starting from zero balance.
Since I managed to build my bankroll up to 7k starting from freeroll now I think I should do away with them because they are sucking too much mental energy and screen real estate.
But why quit from it when you get to play from literally zero money to 7,000? A game of poker may be energy consuming but if you are playing with zero bankroll and end up with 7,000, even stress could go away. Remember that people are spending so much money on poker and other gambling games to drive away stress. But here you are having stress by playing with no money and even making a lot from it. It's very lucky for you to have a casino like that which offers free games and allow withdrawals without a deposit.
