Go into the weekend wiser and with more experience than a week ago.
Sum up your week – what have you achieved, what has failed, what have you done right and what wrong. Congratulate yourself on your successes and learn from the things that went wrong (DON’T punish yourself or feel bad about them. It was a lesson not a failure!). Think about the next week. What do you need to work on to not make same mistakes anymore. What do you have to do to get closer to your goal. Organize that week.
And now go rest. Go enjoy the weekend. Turn your mind off, be here & now and get back to work on Monday with new motivation and new energy!
