How about getting your friend a book on self-improvement? You could consider titles such as "Atomic Habits" by James Clear, "The 7 Habits of Highly Effective People" by Stephen Covey, or "The Power of Now" by Eckhart Tolle. You could also look into purchasing a journal for your friend, along with a set of colored pens. This would allow your friend to write down their thoughts, goals, and ideas as they work to improve themselves. Additionally, you could consider purchasing a gift card for a session with a personal trainer or life coach. This would give your friend the opportunity to work with a professional to create a plan for their self-improvement journey.
