If you believe you're skilled at sports betting, enough to pick the single best game daily.. could you actually discipline yourself to bet just once per day for an entire season to prove your profitability?
Personally, I'd struggle. The urge for more action would get to me. Even starting with one game, a loss would leave me feeling unsatisfied, tempted to chase and recover immediately rather than wait for the next day.
I would do it on a separate account just to test my ability. Though, if I really have the skill to bet accurately on the winning team in sports betting, limiting myself to just one bet per day would be really difficult. I will not limit myself to just one game, I would definitely bet on more games for higher profit. And I'm sure everyone will do the same as mine if they are capable of it. Greed is always present in our human nature so when there is a huge chance to grab something we want, we will always maximize it to full intent.
You should try to limit to just one bet per day so you don't go deeper in gambling. But if you can not do that, I guess you will deeper without you realize. That can make you slowly become addicted to gambling because you will place your bet every day. Yes, greed will always present in our human nature but we have ability to control that so we don't get a bad thing such as losing our money too often in gambling. The temptation to place more bets will be there so we must try to hold ourselves not to spend too much money unless you are agree with the risk and can accept it.
