Hear your voice clearly in your head. Start treating yourself the way you want others to treat you. Make the voice in your head your best friend and your biggest supporter. It is this voice which will either make you or break you, which will either shape you or destroy you. Everything else is inconsequential.
Change your internal dialogue and you will for sure see a change in yourself. Being positive may seem a bit theoretical at times but overcoming negative thoughts is something which is most important. Listen to your inner voice because it will never guide you on the wrong path.
All the change that you want to see, starts with you. If you want to change anything in the external world, the first step you need to take is change what is inside you first. You can love yourself and be your biggest supporter, mentor, motivator or believer; and at the same time, you can curse yourself for every mistake of yours and be your own critic because that is what the society has taught you.
Life is like a boxing match wherein defeat is declared not when you fall but when you fail to get up. Every single setback that you come across in life has some purpose. They help you grow to your best self. Know and claim your inner power, peace and purpose. Pull on your socks and get going because only you can know your true worth.
