        When you are feeling unhappy or forget how great you are, these are six ways to make you feel good

about yourself. 

       ●Look at the mirror and say to yourself "I am a special person and there's no one in the world like me. I

can do anything!" It may not sound good, but it really works!  

       ●Do something nice for someone. Helping others always makes you feel good.  

       ●Smile! Be friendly to people you meet. Look for the good things in your friends and family.

       ●Learn something new! Have you always wanted to decorate your own room or learn how to swim. Go

for it! New challenges are fun and give you a sense of accomplishment when you have finished. 

       ●Read and start a diary. Turn off the TV and let your imagination fly! Write down your thoughts, dreams

or anything you want! Writing always helps to express your feelings. 

       ●Stay with your family. We all need our family time. Talk with your Mum or Dad or maybe even your

cousin.
