One of the most difficult things in life is setting your own goals. Whether you want to become a billionaire, to live on Mars, or to figure out the cure for cancer, what matters most is to have a strongly conscience of why you do what you do: to achieve this goal.
It is not who you are that matters, it is what you want to be. Because what you want to be defines what you do. And what you do defines you.
After one year of reading books, watching inspirational speeches, going through hundreds of blog posts about productivity and reaching goals, and trying hacks and tweaks, here is the most important quote I remember.
The secret of getting ahead is getting started. – Mark Twain
You define your goal, then you just start working towards it. Today. Period.
