Your habits play a big role in who you are and how you wish to change.
Change that lasts, i.e. reaching your objectives, is the consequence of everyday habits, not a one-time shift.
What exactly are your objectives? What exactly are you hoping to alter? It doesn't matter what it is; you got it because of your behaviors. What you look and feel like, as well as your success and relationships, are all influenced by your habits and our brains are easier to control when we have habits.
Habits help us preserve brain capacity — or rather, they allow us to think more creatively.
Making habits out of the things we do on a regular basis, such as our behaviors and activities, gives our brain a power or effort-saving mechanism. We need less originality and depth of thought when we use an instinctive answer.
