"You may not hear about what he´s doing..."
Ok, I won´t comment on this sentence.
"He´s currently working on two interesting things that I can`t mention."
That sounds - at least - interesting. But on the other side, we heard this for years now. So it starts to get a bit boring. BUT in the end the result is what counts!
"He`s doing really well."
The shortest but most important sentence here.
