It is essential to realise and appreciate the power you have over your thoughts. One can have a bad day simply because they entertained a bad thought. You may not necessarily be able to control what comes into your mind, but you can definitely control the way you react to it, together with the length of time it stays in your mind. And that realisation is a game changer.
The connection between these two concepts is simple: in order to better yourself, you need to first love yourself. It’s principal to accept who you are and love yourself for it. All your strengths, weaknesses, powers, and flaws. Only through loving who you are, can you tap into the magnificent world of bettering yourself.
