On your path to personal development, always remember to ask questions. Never take information at its face value. Everything comes with an intention and a deeper meaning. Investigating new information allows you to compare it to your base values and current knowledge, which will help you decide whether it's useful to your purposes.
Influence your moods with food. Eat more complex carbs to help curb anxiety. To increase your alertness, add more protein and foodsd rich in essential fatty acids. White fish and salmon are great foods for this. To lift your spirits, add foods like turkey, lettuce and salmon to benefit from the protein and naturally-occuring tryptophan.
