I've only just started taking poker seriously and playing more regularly.
I'm currently reading/watching through the Cardschat 30 day poker school to try and better understand some of the theory etc while playing (it's been VERY informative so far so hats off to the creators)
I'm relatively limited in terms of free cash (and have had to learn my lessons on budgeting etc in day-to-day life the hard way, but that's another story). Obviously, I won't want to invest money I don't have so currently I'm limiting myself to putting about £10-20 per month into the pot for poker and looking to hopefully bolster that a bit more with some wins (and some freerolls hopefully as well) and see where I go from there.
If I lose £20 a month I can live with that, and ultimately I'll have had some fun whilst doing it
