As we reach further and further beyond previous boundaries in space, science and other areas previously thought of as limited and beyond reach, we continually make discoveries and "update" old discoveries to the truth that we see in science, transportation, outer space and in our own milky way. Isaac Asimov, Carl Sagan, and others wrote and spoke of fact and fiction but as scientist Albert Einstein said "Imagination is more important than knowledge"
After all, many visionaries like Jules Verne wrote of fantastic new vehicles and hidden places under the sea or other planets and other magical things that have come to light within our lifetimes. If you move closer to spirituality, you may see things known centuries ago as well as things believed are as ancient philosophers stated but some may have been misgivings for other purposes. Still though, the answers are within and available to everyone.
What have you imagined but then thought of your own known boundaries and short reach, or the beliefs of others were allowed to limit you, by you? We grow, we learn, we age and "When you stop learning, you start dying" (um Einstein quote again) so how do we update our limitations?

Other than meditations and looking deep within, ask yourself "why" when you find a negative thought is telling you that you can't or shouldn't do something. Write down your successes in everyday life and don't sell yourself short on the little things you do. Then when an automatic negative thought or A.N.T. comes to mind, call it out with "you're lying, this is not true" and quell it. Self talk is done subconsciously so talking back to your self talk is allowed too, though you may not want to do it in public unless you have a cellphone to your ear.
New inventions, new businesses, new ways to help others, new goals achieved, all happen everyday.
So may tomorrow be your day to shine on you crazy diamond (Pink Floyd youtube video) like a diamond in the sky (Rihanna on youtube) and achieve all of your goals in all areas of your life.
