If you tell yourself something often enough it becomes truth, so why not tell yourself something good? I think I'll tell myself that I AM AMAZING!!!! Ha-ha! How about you? (No worries - self-love is encouraged here.) The truth is that you are whatever you tell yourself you are. If you repeatedly think - which is a way of telling - you are too fat, too skinny, too short, too tall, too .... and the list goes on, then you will be.
Instead, begin to repeatedly think and talk about yourself as genius, beautiful, wealthy, healthy, confident, tall enough, thin enough, lovely enough, a great cook, an excellent socializer, an awesome mentor, fantastic at your job, loved by all who surround you... and, again, the list goes on.
Be consistent in your efforts to become who you want to be and who you really are and you will naturally transform into that - you are all there is.
Enjoy your journey to wholeness.
