I Love reading books of Andrew Matthews.Some of his works are: Being Happy, Follow your Heart and Happiness now.It tells about coping through life's difficulties, real instances and how to get over it. Here's some of his tips that is very true and should be applied on our day to day activities:
"YOU GET MORE OF WHAT YOU DWELL UPON" - when you are thankful to God for what you have- for the friends you have, and for the good things you got-you attract more good people and good things.
People who always complain about what they don't have, stay stuck. Complainers attract more things to complain about..
Just be happy with what you have now and more will come to you.. Everytime you say a silent word "thank you" to our Creator you become more peaceful and powerful.
This is a helpful tip especially if we have a bad day. I even post this saying on my signature emails. :)
