Why would you leave it to luck? I am personally a true believer of "you are what you think, you will have what you think." There is a book called as a man thinketh by James Allen. This book published in 1903 and deals with the power of thought. However, that is actually taken from the bible. The full quote is “for as a man thinketh in his heart so is he” Proverbs 23v7. You have to put the effort and the work in because luck can't give you your future happiness—you do by your thoughts, your actions and your words.
Remember, everything is a matter of perception and not every perception is real. Granted as they saying goes “your perception is your reality”, however if your perception and way of thinking is flawed then your reality will to be flawed Is the cat walking up or down the stairs? What is your perception of this illusion and is it correct?
