The underlying principal to enjoying your work and your life is enjoying yourself. That means more than being carefree. This literally means enjoying the space inside your mind, heart and body, not things of the external. Think about your internal dialogue, is it polite and enjoyable or are you constantly ridiculing yourself and others? Pay close attention to this and make sure it’s enjoyable, make it fun and kind and funny. Say things to yourself you wish people would say to you. Crack the jokes you would crack with your best friend.
You see, 100% of how we experience life comes from within, our inner dialogue and which feelings we CHOOSE to adopt and explore. Don’t like the way you are feeling? Choose another emotion. Don’t like the way things are going? Choose to experience it in a different way. Felling sad or heavy? Think of something funny and light hearted. Feeling weak and tired? Think about something that makes you feel strong and allow yourself to feel that strength and energy. You are the master of your internal world, it is your sacred domain, do not allow it to be anything but exactly what you choose it to be. You have no control over the outside world but, when you take control of your inner world and how you choose to experience things, you will find the outside world never was that important.
Now, go out there and be awesome, be creative and be grateful and happy. If 
something is not going the way you prefer, simply assume it is going in such a way that will lead to a better outcome than you had anticipated. THIS IS THE KEY TO EVERYTHING! You don’t need to know why or how, just know that it is and in time it will be revealed. How you experience things is 100% your choice and sole responsibility, this will not only determine your happiness but also your health. Stop choosing feelings, thoughts and experiences you don’t want, simply select another feeling and do what you love with the most noble and honorable intentions and of course a sense of humor, you will never fail!
