#5 KEEP GOING

Challenges can be sometimes challenging (Captain Obvious here :D). So that I want to keep you on the track. 

Here's the one old youtube video, that I found very interesting, motivating, and sometimes even very surprising.
Check a few quotes from the video: 

First Program I wrote asked - What's your favorite color 
Drew Houston, created Dropbox
Coding is something you can learn
Chris Bosh, former NBA allstar player
You don't have to be a genius to learn Coding
Vanessa Hurrst, Co-Founder of Girl Develop IT
Everything depends on computers, and none of us know how to read or write the code
Will.I.AM, lead member of the musical group Black Eyed Peas
The programmers of tomorrow are the wizards of the future, you’re going to look like you have magic powers compared to everybody else
Gabe Newell, Valve (game developer e.g., Counter-Strike)

I highly recommend watching it :)
(I didn’t know that Will.I.Am is so big a fan of informatics technology :D.)

So come on, wizards, YOU can do it.
