Reading this quote this morning from Marcus Aurelius reminded me that there are few limits on us, except for those we impose upon ourselves. It’s not that we can’t do something, in fact it’s often a matter of desire.
Look around you to those that you consider are doing great things and have become successful. Are they smarter, more driven, better educated, or luckier than you? Hell no, you are just as capable as they are. The only difference is they believed they could do it, and so can you. It is rarely the case that we can’t do something, but instead it is our belief that holds us back.
Stop sabotaging your life and start believing in yourself.
Namaste

Smart man Marcus, well… he was the Roman Emperor so makes sense what he said.
