Rules for the mind

One should avoid multitasking as much as possible.

The constant breaking of attention, the switching between different tasks is detrimental to the mind.

The phone on the desk, the cell phone, email, instant messenger - turn them all off.

Don't channel-surf. Don't watch television with commercials.

When driving, drive. The driver's seat is not a home away from home.

I'd say more but I have to answer the phone :)
