Let's assume (for better understanding) that you started with a bankroll of 2000$ that you want to extend.
You set your goal to a certain amount, let's say that in 3 months you would want to raise your bankroll to 3000$. You play, follow the rules, have a good model and a bit of luck (we can all use luck) and after 3 months your bankroll actually rises to 3762$. Reward yourself for good playing, take out 762$ and get yourself something. Leave 3000$ in and set yourself a goal to come to 4000$ in next 3 months. Repeat the process.
Put in whichever figures you want but I'm sure you know what I am talking about. You have a trick and a treat. You need both. Make both the way I described to keep you happy with the little things AND to see your bankroll grow.
The thing that kills us players most is greed. Rather go slower instead of being greedy. Remember, this is also the essence of playing half Kelly / full Kelly.Until you are absolutely certain about estimating your edge, it is better to go with half Kelly (=less greed) and have much lower risk of getting bankrupt.
