Video Summary: Wouldn't your life be magical if you could exercise the self control you intend? Your body would be ripped, your bank account always in the black, you'd always floss, eat right, and get up on time. You'd never be plagued by depression, anger, or anxiety, because you'd will your emotions into compliance.
Self control is the building block of all discipline, the cornerstone of achieving any success. Our mind comprehends our reality as two worlds, the outer world of objects, situations, and people around us; and the inner world of our emotions, thoughts, and beliefs. Humans naturally seek solutions to their problems via the outer world, instead of within themselves. The secret to self-control is to change the paradigm. Instead of portraying ourselves as victims who are acted upon by outside forces, we need to be the creators of our situations and success -- a creator mentality, rather than a victim mentality.
As with instilling any habit, exercising self control requires persistence. Imposing discipline strengthens the pre-frontal cortex's impulse control; while giving in to brain-sapping vegetative stimulation such as TV and internet weakens it.
To improve your self control, own your control via your inner world, rather than blaming outside forces. Unhook from outside stimulation, because you're not in control when you're letting your brain be occupied the lazy way. Instead, read and introspect your way to self control.
