Imagine, if there really was something such as "pure luck"... It would mean that no matter what you do, you have no real control over the outcome of your situation. It would mean, no amount of effort on your part could steer you in the direction of your choosing because all was down to luck.
It would mean you might as well not try...not fight for what you want, believe in, dream of experiencing. It would mean you might as well give up trying and resign yourself to watching all them other lucky people who have everything handled to them on golden plates. All you had left was some form of hope that luck would turn for you.
Now, imagine, if believing in luck (or lack of it) was what was stopping many people from doing their best in what they wish to focus their life on.
You know that saying - It takes 10 years of focused effort to achieve an overnight success? I like it. I think it sounds like said by someone who didn't believe in luck but who got up and barefoot walked a path others couldn't be bothered to walk. It sounds like said by someone who knew there would be many who chose not to notice the scars, the bruises, the cuts but instead saw someone arriving with an effortless smile on their face, happy to have found something of value.
I don't believe in luck. I prefer to believe in invisible but powerful hustle instead ;)
