Reading Tutorials and books are enough to learn??

[Paul]

No its not enough. No book or tutorial is going to give you what you can earn in hand-on experience. Get out in the content marketing world, write something. You may fail but you will gain experience from it and you will apply it in your next test. And if you are willing to get some experienced knowledge first then i will suggest you to find a mentor that's the only way but still you have to work for yourself to improve.
