I am here to tell you that happiness is a state of mind that starts from the inside out. One way to see how happy you are is an external reference on your appearance. When you look in the mirror do you like what you see? If not you are not a happy camper all the materialistic stuff in the world won't change that.
The change comes from within. Embrace yourself and everything about YOU! If you are overweight and smoke you are slowly killing yourself. Start making changes now. By committing to a plan to be healthy starts the wheels in motion to feeling better about yourself. Are you getting enough sleep? How do you handle stress? If you put it all together, overweight, smokes, sleep deprivation how do you think your gonna handle stress??
Start now and start loving you. If you need assistance with a healthy eating plan contact a nutritionist. If you do smoke ...Quit!! I can't over emphasis that smoking will suffocate you. Get help if you need it but Quit A.S.A.P.!
Sleep, Sleep, Sleep. When you are well rested your mind has had a chance to recharge and you would be surprised how that will lift your spirits.
Last, feed your mind good things. Don't watch the news late at night. Stay away from books on poverty and war. Put only healthy books and articles in your mind. Read books on being the best you can be. A good book Called "Thinking for a Change" by John Maxwell or "You Can Heal Your Life" By Louise Hay are two excellent books to start you on your journey of excellent health.
Make it a daily habit to put only healthy things in your body and mind and I guarantee you will be a much happier person for it.
