3. Do a 30-day Challenge. In my experience, it takes about 30 days to change a habit, if you’re focused and consistent. This is a round number and will vary from person to person and habit to habit. Often you’ll read a magical “21 days” to change a habit, but this is a myth with no evidence. Seriously — try to find the evidence from a scientific study for this. A more recent study shows that 66 days is a better number (read more). But 30 days is a good number to get you started. Your challenge: stick with a habit every day for 30 days, and post your daily progress updates to a forum.
4. Write it down. Just saying you’re going to change the habit is not enough of a commitment. You need to actually write it down, on paper. Write what habit you’re going to change.
5. Make a plan. While you’re writing, also write down a plan. This will ensure you’re really prepared. The plan should include your reasons (motivations) for changing, obstacles, triggers, support buddies, and other ways you’re going to make this a success. More on each of these below.
6. Know your motivations, and be sure they’re strong. Write them down in your plan. You have to be very clear why you’re doing this, and the benefits of doing it need to be clear in your head. If you’re just doing it for vanity, while that can be a good motivator, it’s not usually enough. We need something stronger. For me, I quit smoking for my wife and kids. I made a promise to them. I knew if I didn’t smoke, not only would they be without a husband and father, but they’d be more likely to smoke themselves (my wife was a smoker and quit with me).
7. Don’t start right away. In your plan, write down a start date. Maybe a week or two from the date you start writing out the plan. When you start right away (like today), you are not giving the plan the seriousness it deserves. When you have a “Quit Date” or “Start Date”, it gives that date an air of significance. Tell everyone about your quit date (or start date). Put it up on your wall or computer desktop. Make this a Big Day. It builds up anticipation and excitement, and helps you to prepare.
8. Write down all your obstacles. If you’ve tried this habit change before (odds are you have), you’ve likely failed. Reflect on those failures, and figure out what stopped you from succeeding. Write down every obstacle that’s happened to you, and others that are likely to happen. Then write down how you plan to overcome them. That’s the key: write down your solution before the obstacles arrive, so you’re prepared.
9. Identify your triggers. What situations trigger your current habit? For the smoking habit, for example, triggers might include waking in the morning, having coffee, drinking alcohol, stressful meetings, going out with friends, driving, etc. Most habits have multiple triggers. Identify all of them and write them in your plan.
10. For every single trigger, identify a positive habit you’re going to do instead. When you first wake in the morning, instead of smoking, what will you do? What about when you get stressed? When you go out with friends? Some positive habits could include: exercise, meditation, deep breathing, organizing, decluttering, and more.
