Practice Often

The most effective way to internalize complex material, is to practice every other day. This way you will not forget what you've practiced, and will not have to re-do things, but on the other hand, the mind will have time to reflect and rest between training.

Don't start and stop

Make sure you have enough time to complete a meaningful training session. Motivation is an essential part of the training, and the best way to keep it up, is by feeling the progress that was made on each session.

Reduce interruptions

Cut down the possible interruptions from people coming in and out, phone conversations, instant messaging and background noise for a minimum.

Be prepared

Get everything you need a on the table (calculator, notes, pen).
