Jessica Lia/Getty Images Change is tough. It’s difficult to stop doing the same things you’ve always done, simply because you’ve always done them. Routine is a powerful tool to reinforce habits, long-standing and new. The more regularly you do something, the more likely you’ll stick with that behavior over time. You probably want to maintain your positive habits, like having a glass of water when you wake up, finishing off your lunch break with a short walk, or reading every night. If you’ve got some habits you’d like to change, though, you might have realized breaking them isn’t quite as easy as you imagined.
