If we have a complicated mind, which thinks too much about certain things unnecessarily, our attention may be led towards the obstacles, problems, upsets and the things we worry about from a critical and negative viewpoint. By paying more attention to difficulties and problems, we feed these types of thoughts with our attention, so that we end up attracting these situations towards us. Finally, the problems and obstacles absorb us due to the amount of energy we have invested in them, turning what was perhaps a molehill (something very small) into a mountain.
The situation does not necessarily change immediately on changing our attitude. With this inner change, however, we will have more energy, clarity and determination to face up to and change the situation. When we focus on seeking solutions to problems and difficulties with a positive and enthusiastic attitude, we attract positive energy towards us, and this helps us transform mountains into molehills.
