4. Write down 3 things in the evening that you can appreciate about yourself
This is a variation of the habit above and combining the two of them can be extra powerful for two boosts in self-esteem a day.
Or you may simply prefer to use this variation at the end of your day when you have some free time for yourself to spare.
What you do is to ask yourself the question from the last section:
What are 3 things I can appreciate about myself?
Write down your answers every evening in a journal made out of paper or on your computer/smart phone.
A nice extra benefit of writing it down is that after a few weeks you can read through all the answers to get a good self-esteem boost and change in perspective on days when you may need it the most.
