You know what people tell you about success? That it just takes pushing yourself that little extra and you'll get there. And, whilst they might be right in some senses, I think all books and articles on success/growth forget to mention A WHOLE LOT OF OTHER THINGS.
So let me introduce you to somethings, that I have learned over the past couple of months:
minute; every second - Thats right, routine is important. You need to program it into every single day of your life. If you want to achieve greatness at a particular thing - you need to eat, sleep breathe it. You need to constantly update and more importantly WANT TO update. Your desire to improve needs to over-ride every other desire of too hot, too tired, not feeling up for it, I need a break etc. Its the only way. The mind always seeks to want to stay in 'comfortable' and greatness unfortunately is just outside that circle.
2) Strive for Progress not perfection - The internet/ facebook/ instagram is filled with a gazillion photos/articles of what perfection looks like. For me as a yogi, it is Kino McGregor and her ability to do handstands like it is no big deal, for you it could be Masaba Gupta churning out design after design, Jason De Silva creating this mind blowing videos, it could be anything. But remember this, if you aim for perfection it will be a fast and very painful decent into misery-land. Instead aim to progress. Aim to be better than who you were yesterday.
3) Forget the fear of being wrong - Many times you will be forced to make decisions and sometimes you may never know - if that is the right decision to make, at this particular point of time, under these particular set of circumstances. But you know what, you need to give yourself the permission to be a beginner. The only way you will know is by trying. Dont let inaction take control of your mind and body until the opportunity passes. And last but not the least don't be a shadow boxer- someone who lives in a land where they are caught between the dream of action and the fear of failure.
