Being able to do two things at once is a big part of success. I try to do abdominal exercises, isometrics, even when I'm at a meeting. Tensing... holding... and then releasing. I'll even floss in the shower while the conditioner is in my hair, during the part when you're supposed to leave it in. Those things can really add up to a significant time savings.

черт побери, откуда они знают?)
