Remember the old wisdom that the people have power only over the current day. The future is shaped at the moment, and the past cannot be changed. Constant worry is not able to do something constructive, so there is no point endlessly to build the scenarios. Autocyte yourself from scrolling in mind negative situations. Of course, radically once and for all to prevent yourself it will not work. So allot yourself some time specifically for this, for example, during training (instead of the music player) or in the evening - one hour to devote to planning, during which you will reflect on the bad. Time is up – take care of business today. And no concessions themselves.
Train yourself to enjoy the little things in the morning. Nice shower, delicious Breakfast, hot coffee for a special recipe, a cheerful voice leading on your favorite radio - all this should be part of a special ritual beginning of the day. It distracts from thinking and allows you to feel the here and now, enjoy every minute of it. When washing dishes, rejoice as it becomes clean again, and do not wander in the labyrinths of the mind (and the dishes will be more whole). In every single minute, try to do everything more efficiently. And then in the end you don't have to worry about the results. Simply because every moment was a success.
Remember that tomorrow is the ability to do something may not be. So act today, and do sit down at work right now. Do as one of the famous people, put yourself on the desktop with a sign that says "today". After all, this is the most important day of your life, because it can be changed, he can clearly see and projected much better than a vague tomorrow. Things are changing so rapidly that you should only count on today.
