The idea of how powerful a thought can be is truly astounding. It has the power to manifest itself into existence by merely starting from a tiny seed in the mind. The more you think about a thought, the stronger it becomes. Because it occupies a significant portion of real estate in your mind, this will eventually translate into your perspectives, actions and other areas of your life. If is a positive thought, then that is wonderful. However, if it is negative, then you need to do whatever you can to distance yourself away from it. Anything that directly or indirectly, i.e. triggers, results in that particular thought. Do not water it any longer. And as for future negative, disempowering thoughts, do yourself a favour and nip it in the bud. There will be more than enough challenges in your life so do whatever you can to give yourself a fighting chance to overcome them.
