Write down your achievements Similar to a gratitude list, jotting down a few of your accomplishments reminds you that you can achieve things and eventually get through whatever it is you're going through right now. If it's work or study related, write down projects or assignments where you worked hard then received positive feedback or a high grade. You don't need to keep the list as the process of creating it is relaxing in and of itself.
