In comparison to using your heart to inform your decisions, a bet placed on the back of you doing your research and is not influenced by factors such as the team you support is a better strategy and one that will create an experience of value in the form of entertainment.
By removing the emotional element, you can make decisions which are based on information relevant to the event.
You will also be better placed to reflect on the outcome of your bets and give you an opportunity to learn from your previous bets, improving your decision-making process moving forward.
