You need to be organised if you want to be successful when it comes to losing weight. Eat better, eat maybe a little less, move, play sports... Give yourself every chance! Make a list of what to do during the day and cross them off as you go! Be courageous! Stay motivated! Stick to it! Don't set goals that are too ambitious in the first few weeks. Don't try to run an hour each day when you've only just started running! Don't try to lose ten pounds in a month! The essential thing is to be demanding of yourself but in a measured and constant way. Perhaps you could try to make an appointment with a dietician who will help you come up with a plan of action! You could talk about how you live your life and come up with clear and precise steps that are relatively easy to achieve!
