Bankroll Management... Are you serious?

So a week or so ago I started to build my Gutshot bankroll. I started with a roll of $400 and had my ups and downs first week playing at the wrong level (ahem!) as per usual. This last 9 days i've been playing mostly $0.25/$0.50 and i've had a pretty good run at it. I can't say it's got my blood pumping, but at least it's been profitable and i've not been risking my whole roll. Over the course of 5 days playing on average 2-3 hours a day (i fade after that online!) i'd moved from $400 and change to $1,500. Now normally at this point i'd rock on upto a $2/$4 or higher table and 'take a chance' at a higher level. This time however I decided change the goalposts...

Rather than continue playing low limit poker I would make a deal with myself. If I could build the $1,500 into $2,000 I would take $300 of that and play a little $2/$4. So I ran it up to $2,250 in a few days and banked some of it ($250) before playing at a higher level. Now if I lost the $500 I would have to start playing low limit again, but as long as I bank $250 a week I'm free to play the game which are a little juicer!!

I've had a pretty good few days so far including this session yesterday.

My high so far is nearly $5k, but at the moment i'm down to $3,800 of which $2,500 is my drop down line. I've had most success playing $5/$10, but i'm going to try and play mostly $1.50/$3 or a little higher. They seem fairly easy and at least at no stage am i risking it all. I'd be interested to know what people's thoughts are on this method of bankroll management?

Anyway, had my little girl over yesterday and it was her 7th birthday today so i'm knackered after helping organise her swimming party for 15 of her friends!! Tonight I plan to play a little poker at the Gutshot followed by golf tomorrow. Splendid.
