Interesting article about how to change your long-term behaviours. I’ve managed to stop biting my nails (I know, I know), become pescetarian, and largely give up drinking coffee through similar advice:

Any habit you want to build takes practice, and the recognition that you’re not going to accomplish it immediately. Whether it’s saving more money, or running a few miles, or learning about classical music, you’re not going to experience a dramatic shift and suddenly have $10,000 socked away, or be able to run a marathon, or know Mozart’s entire catalogue. But if you’re dedicated and commit yourself to something over a long period, microshifts will get you where you want to go.
