That person is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither— whatever they do prospers.
— Psalm 1:3

Yes, champions are made behind closed doors, that is where the dreaming takes place, that training, the mindset conditioning, but never ever the 'epicness' of any man.
If no one knows you, your one will know what you are capable off and therefore cannot celebrate the genius in you.

Open the door and step out of your comfort zone.

As much as many people need to leave their physical and pursue their dreams, many more people need to open the cage of their minds and set their soul free.
You know it isn't that you don't know what you want to do.
You know it isn't that you don't know that you can do better than you are now
You know it isn't that there is not much more than you can offer

You simply are trapped in your mind, and that is Ok, as long as you decide not to stay put from now further. Why? There is the world out there waiting for your light to shine so they can lit there from your candle stick.

Imagine those days when you thought; “I wish I knew then what I know now?” 
There is someone 'there' now in use of what you have learned. Those knowledge are not to use be archived and left to go waste. No, it can save someone's life, even if it is ONE, and that is an amazing starting point.

…... No one can hit their target with their eyes closed
— Pablo Coelho

Here is a track to EPICNESS
1. Decide what you want to do – without any iota of doubt
2. Draw a map of how to achieve it – from the end back to where you are now, they find your way forward
3. Break your map into bits that are easily achievable and connected to the next goal.
4. TAKE THAT FIRST STEP and the next
5. Celebrate each goal no matter how small.

Don't let the absence of speed make you give up. Giving up is as bad as not starting at all, in the end, nothing is achieved. That is not the end goal you have in mind, I hope.

Remember, you are setting out from the place of victory. It is settled whatsoever you do you shall prosper. All said and done, ready, set – GO!
