When you climb up, you never know whether there will be a zenith. You must feel the weigh of world on your shoulders, you must pass all drawbacks and see the smooth way you open when you look back. Just be patient. You will see how it will work. Everything is under your feet. You are the one who will take all of them and turn into a solution. The problem is not how you can do it, it is how they can stop you. It is worth to try.
