Developing concentration takes practice and time.People tend to underestimate external stimuli. If possible, turn off your phone or the sound on it, turn off notifications, find a quiet room without people and unnecessary sounds.Attention can be compared to a flashlight. If you shine it on one area, it will be well lit and you will be able to clearly see all the details in it. If you try to spread the light from the flashlight over the entire room, you will see much fewer details, since the light will be very weak.One way to make a task more interesting and your work more comfortable is to create pleasant conditions. Check if your workplace is comfortable. Your back doesn't swell, your neck doesn't get tired.You can light an aromatic candle or place a plant on the table to look at during breaks.
