Be your best. The best girl/boyfriend, employee, cook, reader, artist, thinker, student of the universe. Any doubt of your ability to follow through with these things will only seal the exact face you wish to avoid.
-Don't take things personal! Most of what people say has nothing to do with you, even if it seems to be directly about you. When you're feeling good, do you feel the need to say negative things to people? Hurting people hurt people. Have compassion rather than responding in anger to critical or judgmental people.
-Don't over analyze things. People are so good at torturing themselves. Buddha was right when he said that "Your worst enemy can not harm you as much as your own unguarded thoughts." You have to live in your mind all day, and you're the only one who can choose the decor. Is your living space enjoyable or painful?
-Be present and aware, respond to your environment rather than reacting to it. Be slower to respond to things, catch yourself each time you feel yourself wanting to label or define everything you see or hear. This is a reflex of a know-it-all and we've all been guilty of it. You don't know everything and neither do I! Practice being okay with not knowing.
-Drink a lot of water; this helps physical energy and mental clarity. It makes your skin look better and your system feel cleaner. Yeah, you might be taking a lot of trips to the bathroom but this is just a little extra exercise.
If you're feeling disenchanted with life, look at it as though you're seeing it for the first time. As though you've just been given a body as a vehicle to explore your surroundings in. None of this is yours, really. It all came from the universe and to the universe it will return. The world will not accommodate those who resist the natural order of things. You'll be left dependent, lost, or disappointed.
Expect nothing, and gain everything... most of all, insight.
Know that no matter how any situation ends up, you gave it your best. This way you can never have regrets.
