One great idea for your friend who loves self-improvement would be a subscription to a self-help or personal development book club, like "The Personal Growth Club" or "The Life Improvement Program." This could provide her with regular doses of inspiration and tips for achieving her goals. Additionally, you could also consider gifting her a journal or planner specifically designed for self-reflection and goal setting. If she enjoys fitness, you could also look into a membership to a wellness studio or gym that offers classes in yoga, meditation, or other self-care practices. A weighted blanket or aromatherapy diffuser could also be a relaxing and restorative self-improvement tool that your friend would enjoy.
Or you can get her/him a star map with the date of the wedding.
