"The only person you are destined to become is the person you decide to be", says Ralph Waldo Emerson.
God has a reason for giving us imaginations. He called us, predestined our end, justified us and sent us to leave a great impact as a purpose of our lives.
Fortunately, He established in our reasoning faculty, a school of thoughts which is where we imagine our state.
Our imaginations take us on tour into the future, so that we can see the brightness of our destiny and come back to make plans towards fulfilling it! By that means, we are able to make rightful decisions for the realization of our real-selves.
Decide on the positive things you will pursue! Desire a very useful use of your brain. Never think of immoral and useless thoughts. Your positive thoughts are your future visions!
