There are three elements I can think of that I should have before I start betting:
MONEY;
Of course, you need money to bet. Signing up for a casino is free, but betting costs money unless you want free bets, and you are limited to the casinos that you can find online.
TIME;
To enjoy your gambling experience, you have enough time; your time should be commensurate with the money you have.
MOTIVATION;
To fully concentrate on your enjoyment and your chances of winning, you need to have motivation; it's not worth spending your time and money if you don't have the motivation to gamble.
I make sure that I have all of these elements before betting, how about you do you have all these three elements before you start betting?
I can understand your list but i don't agree with the list especially motivation. Money and time matter, thats true but motivation is actually the most dangerous thing to bring into gambling. It is very easy for your motivation to shift from pure entertainment and thrill to "i want to win or i want to make money" once that becomes your new motivation, then you are done for it. Gambling is the last thing you should be motivated to do. And then having money doesnt mean you should gamble. it has to be money you are already okay with losing, not your life savings or money you are hoping to multiple through betting. Too much free time can actually lead to overplaying and chasing losses so you need to be strict with you betting time. Before betting ask yourself this "if i lose this money and stop right now, will i still be fine? if the answer is no, dont bet, you will not be doing yourself any good.
