I usually don't have a lot of free time, but thought I'd just rant and share some thoughts on my process in betting.
In NBA, almost never fade teams that are sitting star players. See today, Irving and Doncic sit, Mavs cover. Giannis is sitting and Bucks currently winning. Haliburton and Turner sit and Pacers cover.
Pay attention to early and late line movement. That's really the only line movement that matters. Sharps hit early and late. Everything in the middle is public. If anything, fade middle of the day line movement.
If a line looks to good to be true, there is usually a reason for it. I always use this rule of thumb, swing the line by 6 points the other way and flip the home and away teams and see if the line looks about right. For example, Celtics were -5.5 on the road today against ATL, that was definitely a Boston line, they would have been about -11 in Boston.
Take dogs and stay away from favorites, they cover a lot.
