The truth is there is no such thing as actual reality, there is only your perception of reality, your perception of reality or interpretation of it comes from conditioning, it comes from conditioned beliefs that have been ingrained in you, throughout your entire time on earth, from people who influenced you throughout your life like parents, friends, role models. Evething that has brought you here has reinforced your beliefs and created your model of the world, and therefore influences how you see things, influnences your reality. Knowing this, you can question and change the interpretations and the beliefs that do not serve you in a positive way, you can choose to see the good in the world, you can choose to see the failures as lessons that strengthen, you can choose to see struggles as blessings sent to make you stronger and build your character.
