Be grateful for something every day. When you look at people try to pick out something of value in them.
Don't hesitate to acknowledge this. Compete with better standards for yourself. Competition with others is dispersive of energy. Acknowledge their value and see what you can contribute.
When others succeed, then you will too. Remember to focus on the big picture. It is not about winning arguments, but rather about bringing ideas together for mutual growth and accomplishment.
Remove the negative things from your life. Practice saying what you want in life and then visualize what it takes to get there and what it would be like. Don't focus on your mistakes and start over everyday.
Know that your mind takes in what you expose it to. If you want more good things seek out more good things and avoid the negative inputs.
Be good to your body, it houses your spirit. Know that there are many kinds of beauty and that not all of us see it the same way. That in itself is beauty. You will better love others when you learn to love yourself.
