Sports gambling are not easy to play just like dice or slide gambling. Here in sports gambling we not only depend on our luck but we need to have good study about the teams their player, and to make a good strategy for playing sports gambling.
It's actually easy to do. You can just bet blindly and let the luck do the work but that's very similar to just playing in dice. The advantage of doing sports betting is that you can do the research ahead of time and be able to determine which team is better than the other. On the other hand, things are still undecided and sometimes even an obvious win can be a surprising loss. Luck still functions in sports betting.
Knowing your limits is a good thing, but sometimes its hard to execute specially if you are almost reaching your limits and at the same time wanted to recoup. So its really important to take control of your brain because we all know that almost all gamblers decision making are clouded when everything is not going on our way.
The thing with us, humans, is that we're so good at planning but at the time that we actually have to execute our plans, that's where the problem seems to arise. In order to fix this, you're going to need to learn how to discipline yourself. I recommend checking out subreddits
/r/SelfDiscipline and
/r/getdisciplined. Sort it by "Top" posts and then choose "All time" so you can see the posts with the most upvotes. They are often a compilation of good articles about getting disciplined. They can also be posts where OP is merely sharing their experience about discipline. It's definitely worth checking out because it's a community. You are trying to be disciplined with other people that are helping each other out. It's said that it's easier to fight your demons if you fight it together with the help of other people fighting the same battle.
I'm pretty sure that there are posts about gambling in that subreddit as well which can totally help you control yourself when you've already reached your daily limit for your gambling habit.
