Based on the fact that your boyfriend enjoys giving advice, I think a personalized advice journal would be a great and meaningful anniversary gift for him! You can purchase a blank journal or notebook, and then decorate or personalize it with a message or image that's special to the two of you. You can also divide the pages into different categories, such as "Relationship Advice", "Career Advice", "Life Hacks", etc.
In the beginning of the book, you can write a heartfelt message explaining how much you appreciate his advice and how helpful it has been throughout your relationship. You can also encourage him to use the journal to jot down any new advice or ideas that come to mind, and to reflect on his own experiences and lessons learned.
Another idea is to include some writing prompts or quotes to inspire him to write. For example, you can include prompts like "What's one piece of advice you wish someone had given you when you were younger?" or "What's one thing you've learned from past relationships that you want to carry forward?" Adding some creative or thoughtful prompts like this can help him reflect on his own experiences and offer even more meaningful and personal advice to those around him.
I hope this idea helps inspire you, and that your boyfriend loves his anniversary gift!
