Yes! Your Life you are experiencing right this moment was brought about by your perception!
For example: What is your perception of someone who doesn't finish High school?
Is your perception in this case actual reality?
More than likely not.
So if you want a different life or want to start living your best life you must adjust your perception!
Is that new task, that will take you to your next level really that hard or is that just your perception?
New reality, new perception!
