I will tell you my story. I started on 888
4 months ago from zero and actually never deposited. As a begineer I only played freerolls as much as possible (since it was the only thing available for me). After some small ''in the money finishes'', I managed to go deep into one freeroll, and finished 2. earning $6. Since then, I never looked back and started playing small DoN (Double or nothing SNGs), as small as 55cent and later $1,1. I had a feeling for the game and soon enough built my bankroll up to $50. Nowadays I have almost 1k profit on 888, and looking to make a transition to cash games.
This is my story, but if you have any start-up capital, you can try micros 0,01;0,02 and grind a lot. Plenty of fish out there, especially on 888. BUT the most important thing, if you are just starting with poker, try to read some books(my recommendation : ''Harrington on holdem'' will teach you everything you need to know if you are beginner)
and play solid tight-aggressive style from the beginning, later you can loosen up a bit if you feel comfortable enough.
