Shifting is about changing your thoughts (and therefore your beliefs and feelings) about yourself.

When you turn inward and focus your energy positively upon yourself, you shift to a place of love - and therefore, higher vibration.

The rest of the external world around you will then rearrange itself (seemingly shift) to meet your new vibration/existence - which is based on your thoughts/beliefs/feelings about yourself.

When you turn your thoughts to yourself in self love and positivity, there is no struggle.

And things become easy - because you are giving yourself the greatest gift - love.

Your external world and your "reality" shift as YOU shift - with your thoughts and feelings and beliefs.

There's no effort or struggle in trying to shift from one reality to another - or at least there shouldn't be - because reality is in your consciousness - so if you fill your consciousness with good, positive thoughts and beliefs and feelings about yourself, that is what you will experience "externally" - because you're living it internally first.

Hope this makes sense and is helpful.
