The best over time?

I have a friend and coworker that I have been working with for 25 years and recently we have been traveling together. I am thankful for so much in this relationship but here are the quick ones. 1. He keeps it simple 2. No drama 3. Ability to handle almost any situation 4. Blending into any enviornment 5. Able to have fun 6. Consistent OK not mind blowing but sometimes you appreciate the simple things in life like a good friend.
