Since a year now I start my day writing down 10 things that I am thankful. Then I workout for 30 min. Could be Yoga or some cardio.
Then when I have my breakfast I write down the goals of the day. Not a to do list...for me "to do"is a must. And a lot of times with a must I go the oppisite way.
And when I feel a bit lost at one moment then I check my Goals of the day-list.
Try to read the book ....he's just not that into you. When I was dating it was really an eyeopener for me.
And before I go to bed I write again 10 things that I am thankful for and send love to 3 people that I truly care about. It's an excersize from Bob Proctor.

And try to enjoy the little things in life. You will get there....I believe in you.
