You cannot combine gambling and work because it will reduce your performance. As you said, when gambling we will think about strategies to win. It requires energy and focus and you can't divide it between work and gambling. Your boss will scold you and you will not be productive at work. You also cannot enjoy your gambling because you do it during working hours. I can't imagine what it would be like if I were in your position because it's very unpleasant when you can't enjoy the game you're playing.
Your performance can not be reduced when you have done all your work
It is Friday and there is 1 hour left to work. Do you think someone is going to push himself hard during that one hour? Of course not. Especially on a salary day. Even the clients would come or call unobtrusively, as they understand that everyone is about to run home after a working week.
Of course there are jobs the require focus and working hard. Not everyone can make a pause and take a rest during work. But nobody is killing himself at work. There are rare cases, but such people are few.
I understand that point, and it's very true, to think about what you're saying, there's a lot of reason when doing purely physical work, but even so concentration is required, but in the case that, for example, I sometimes have to do automation and control work. of a PLC for a certain process in a company, I need time to make my control plane to see if it is compatible with that of the engineer who sends it from Germany, or any other country, then I carry it out with the connections, it is worth highlighting If I make a mistake in one of the connections I am capable of killing many people because they are in a room that could be energized, and that is very delicate, in fact many engineers have lost their license for things like this, and that is true. It's sad just to realize that I'm in that job and then because I'm playing I start to see that I can lose a lot in the casino and I leave aside the work of energizing, but I forget and I do it, just because I'm playing in the casino using the telephone, that could cause many deaths, and that is totally irresponsible, apart from the fact that they put me in prison.
So in this type of work I don't recommend that, now it is a job that I also do, for example carrying optical fiber for the community or the Internet, it is a field job, I have to go by car, it takes me some time. time and even so I go to be able to see my things well and on the trip that I was in the car, there I was able to take my phones and play calmly, but that is another thing, it is another mention of seeing the game and yes, it can be applied , but it is something that I do not recommend doing, because even though it is a boss job I am going to need concentration, first to get out quickly and second so that the things I am going to do are completely planned, that is what I call a good system To do it, there are also people who when they do maintenance on machines use the 6WH method just to do it faster, which is a very nice technique, and it also requires concentration.
