Insecurity is the lack of trust in your abilities and worth. When you enter into a secured state of consciousness, everything that helped boost your confidence will return.
You can perhaps, in a number of circumstances, tell yourself that you can't have more than you have until you do better than you're doing, but by all means steer clear of its reverse, the creed of defeat, in saying that you can't do better than you're doing until you can have more than you have.
When there is silence, Give your voice. When there is darkness, Shine your light. When there is desperation, Offer hope.
