Always look on the bigger picture. Professionals don't focus on one game or on one day. The job is always done before the game. After the game starts you don't even need to watch it. If betting is stressful and if you can not sleep because of this, you are doing wrong. If you pay too much attention to a single game, if every single betting day is too exciting for you, then something is wrong. Maybe it is wrong strategy and you bet too much compare to your available risk capital, maybe you don't have the edge, maybe you didn't make full analysis,... In general proper sports betting must be boring. Numbers and analysis before the game, money management and goals before the season and then just stick to the plan.
