Life often needs us to take care of ourselves before we can go and accomplish our respective goals. If gamblers followed this advice as frequently as any other gambling tip they follow, they may not even need other gambling tips - if you take care of yourself at the tables, the night will probably turn out okay. Taking care of yourself can change meanings through time and even through a single night at the casino. Any good gambling tip actually promotes this kind of philosophy and among other things, one thing that doesn't change is that taking care of yourself means taking care of your bankroll.
A bankroll should reflect its owner. It cannot be bigger than the owner or smaller than what the gambler needs it to be. It needs to serve its purpose. That means that any gambler making a bankroll needs to know what they're at the tables for. Are they there to blow off some steam or are they on vacation? Is this a once in a lifetime thing or are they staking out the poker and blackjack tables and looking for a new career? These and more questions of the same type should be answered. Figuring out those answers will lead most gamblers to the answer of how much should be in their bankroll. Not knowing what their purpose at the tables is can lead to becoming one of the many tragic cautionary tales floating around.
At the very least, you should be comfortable with the money involved. If not, you're probably committing far too much to it and should ease up.
Your bankroll is something that doesn't remain stagnant. It is a creature in and of itself and has a life of its own. It grows and it shrinks, depending on how well you manage or treat it. Long term players even have entirely separate bank accounts for their bankroll to make sure that they have a clear idea of just how well it's faring. That's an example of the finest gambling tip around that can help you take care of your bankroll - keep notes. Do the basic accounting necessary to keep a close and objective eye on just how well you are faring. What you cannot measure usually cannot be managed.
Your bankroll determines and shows who and how good you are at the casino tables. Take care of it and you'll look amazing. Abuse it and you'll be bankrupt before you know it.
