- Print and decide on the challenge you want to start. Write it on the tracker and hang or insert this tracker in a visible place. You must see this tracker daily to stay on track with your challenge.
- Next, cross every day you’ve performed a required action. Try to be consistent and perform as many days as you can. If life happens and you can’t act for a few days – it’s fine! Just try to catch up the next day.
- Review at the end of the month, to sum up days of successful habit performance. Don’t forget to reward yourself for successful completion!
- Now, try another challenge! Remember – competing with yourself is much healthier than competing with what you see on social media.
