To avoid the biggest and most frightening cons, it's obvious, we must have time to take a break because even though you always monitor the chart all the time it doesn't guarantee you get good results because then you will only get increasing pressure and you will find it hard to concentrate properly. Make your trading as a normal activity like other workers out there who only need 8-12 hours a day and you still have other time to spend on socializing or even taking longer breaks and going on vacation.
Yes, we should take a break to relax and also to reduce the stress that we have from trading. Trading will become really boring if you will do it regularly or by just forcing yourself. It would be better for you if you are going to change some of the routines that you are currently on so you will feel less stressed and you can do other things that you enjoy.
