He always keeps a smile on his face.

I don't know how to solve this situation.

He has overall control of the project.

He has the situation completely under control.

He is a very on-the-ball person, always aware of the situation.

His alertness keeps him safe even in dangerous situations.

I was amazed at his extraordinary talent.

He is my best friend.
