Just a remember.
One of the most useful ways to feel good and happy is to focus on what it's good in your life. I don't know why we have the use of focus on what we don't have (and the neighbour does), we have our life and our situation, somethings are good, somethings are bad, we can choose what we focus on, it's a matter of habit, when we realize focusing on the bad we simply change, stop complaning and begining thanking
To feel thank and remember all the good things than we have and happen to us along the day is one habit that will make you to feel incredibly better.
kisses, have a lovely day
