Breaking these patterns of behavior and changing your thought processes can be difficult. On a subconscious level you have become so accustomed to your current behaviour patterns — – your subconscious mind resists these changes as it goes against what it knows, and it does this to protect you. A big change in your life leaves you exposed, vulnerable, and susceptible to larger failure — – if it can revert you back to your regular patterns of thinking and behaviour (which it sees as efficient and normal) then it is protecting you.
