1) Know your core values. Don't ever compromise them.
2) Pay attention to your feelings. Its not necessary to react immediately, but allow yourself time to take them in and act accordingly, working in your best interest in the process.
3) You are in no need of validation or attention from others. You exist peacefully as you are, good people merely add to an already contented life. They are not the source of contentment. That is in you.
4) Mind, body, soul. Work towards nourishing and connecting all three in order to attain balance and contentment. Take care of your mind by feeding it positive thoughts, affirmations and setting realistic long term and short term goals. Nourish the body by feeding it that which it needs. And nourish the soul through self awareness, seeking meaning, minimising negativity and using the heart as a guide.
5) Self improvement: keep building and working on yourself and find ways to utilise the skills and talents you may have. Find your self worth in the way that you are, not the way that you look.
6) Know your worth and only keep those who recognise it within your close circle.
7) Have high standards for the quality of love and friendship which you give and receive. It will make your life more beautiful.
