One can only manage to create positive habits by creating certain conditions and knowing herself first. You just cannot think positively by saying it. To do this, you should take time for yourself, stay away from conflicts, face your fears. First, it is useful to note that there is not a single formula that might be appropriate to think positively. One can only achieve positive thinking as a result of certain conditions. In other words, it is not possible to create the conditions necessary to think positively without some other conditions being met.
