4. Knowing how to adjust your diet when you make progress

For diet, I'd start with 12 calories per pound of bodyweight. Use a 40%-protein 40%-carbs 20%-fats ratio OR 50%-protein, 30%-carbs, 20%-fats.
Use low GI complex carbs only and mix in some fish oil and extra virgen olive oil for fat sources.
Most importantly, be consistant
