Hope is real. Imagination is real. They do bring about real big things.
So does procrastination. So does association with energy drainers. So does watching Netflix and not opening up your laptop to work on the project that you must.
Everything becomes real, once you start practising it so much that it becomes a part of you.
The question is not how you can or will you ever be able to do it. Definitely you can do it. The real question is which direction have you made the decision.
