“Your imagination is your preview of life’s coming attractions.” -Albert Einstein

“When I look up at the night sky, and I know that, yes, we are part of this Universe, we are in this Universe, but perhaps more important than both of those facts is that the Universe is in us. When I reflect on that fact, I look up — many people feel small, ’cause they’re small and the Universe is big, but I feel big, because my atoms came from those stars.” -Dr. Neil DeGrasse Tyson
Your thoughts absolutely create your reality. Thoughts are  energy that are sent into the universe and manifested with a time lag of course, as physical matter. The thoughts you think determine the outcome of your experiences, from finances to health, and relationships. There is no aspect of your life that is not affected by your thoughts. So with that said, be very mindful of your thoughts.  Kick out the first negative thought before it snowballs into many negative thoughts and then it’s extremely hard to stop that train. It can take days to feel better, so why don’t you love yourself enough to extinguish it and replace it with only positive thoughts.  You will see your life changing if you only look at the good and what is working in your life.
The mind is a powerful machine that the heart should be in control of.  We all can alter our lives by altering our attitudes of the mind.
Have a great day!
