Trying to learn to Work with Text without using J,K,H,L and arrow keys

I came across this webpage (http://vimcasts.org/blog/2013/02/habit-breaking-habit-making/), which recommends to stop using j,k,h,l and arrow keys and promote use of other more efficient keys to browse through the code. I am intermediate level of Vim user.

I have disabled (temporarily) the use of j, k, h, l (using HardMode vim plugin). It has been a little challenge to work with the code since then. But I know it will help me to be more efficient with Vim.

- I have so far used, w, b, e, ge etc to move around the lines.
- Also have been using f + character to move through the line.
- And have been using little bit of marks and / search to find through the code.


Here is my question:

I find it still difficult to go to next lines or browsing up or down through the text. Can any one please help me with efficient use of working with text without a usual j,k,h,l use? Are there resources or help on internet? What are your strategies to work with text?

Thank you for your time and reading this.
