It can be very difficult to stay motivated due to obstacles and challenges you face each and every day....UNFORTUNATELY, THAT IS HOW LIFE WORKS! But, YOU must believe that you have what it takes to overcome any obstacle or challenge.
Look around you...there is inspiration and motivation all around you. You must be able to recognize it and apply it to your life. People come in and out of our life everyday....some stay for awhile, while others are there for a short time. Try to learn from others and through your experiences (good and bad). Each experience, relationship, and challenge will shape you and push you to get motivated or inspire you to overcome difficulties.
You will come across people that have overcome seemingly impossible difficulties, people who follow their dreams into uncharted territory, people who rise to incredible heights of achievement and success.
Everyone has a story and EVERYONE has overcome something. Tell your story and always be yourself...you get INSPIRATION from one person and then you are an inspiration to another person. It is quite a fascinating pattern.
Never stop searching for your spiritual fulfillment, creative expression, and deep satisfaction in life.
