Preventing repeated use of hjkl movement keys in vim

Question

Since I frequently don't use the excellent motions and text objects that vim provides, (and since "Holding down 'j' is a vim anti-pattern,") I'd like vim to assist me in training to use these instead of using hjkl more than a few times in a row.

When I started using vim, I was annoyed that I didn't use hjkl to move but would instead use the arrow keys. As a reminder not to do this, I remapped the arrow keys to keep myself from using them - I knew using the home row to navigate would be a better long term plan, so I cut out the positive reinforcement I would get by having working arrow keys.

map <left> <nop>   
map <right> <nop>  
# I quickly removed nop's for up and down because using 
#  the mouse wheel to scroll is sometimes useful

I no longer need these mappings in my .vimrc because this worked very well, and I quickly switched, without having to make a conscious effort to do so. In a similar fashion, I'd now like to cut off my repeated use of basic movement keys hjkl as well. I was envisioning something like this:

let g:last_mov_key = 'none'
let g:times_mov_key_repeated = 0
function! MovementKey(key)
    if (g:last_mov_key == a:key)
        let g:times_mov_key_repeated = g:times_mov_key_repeated + 1
    else
        let g:last_mov_key = a:key
        let g:times_mov_key_repeated = 0
    endif
    if g:times_mov_key_repeated > 3
        echo "Negative Reinforcement!"                             
    endif
endfunction

noremap j :call MovementKey('j')<CR>gj
noremap k :call MovementKey('k')<CR>gk
noremap h :call MovementKey('h')<CR>h
noremap l :call MovementKey('l')<CR>l

But this breaks in visual mode, and I imagine in tons of other cases where using the vim command line in the middle of something changes the state when it shouldn't. How can I constrain myself to have to use more complicated motions?

Edit: Question edited after first two answers for clarity, paragraphs reordered. I want some assistance from vim moving beyond romainl's "level 0". So far answers advise me not to waste my time, but what if we assume that I'm a fan of the learning technique where I change my habits by altering my environment to change incentives? In this model I want to accomplish a task, say, scrolling down a page, and I will more or less randomly attempt key combinations until I achieve that task. Dopamine signalling etc. in my brain will reinforce the action which eventually achieves this result. I could focus on remembering not to use hjkl, or I could focus on the task I was originally trying to do anyway, edit text, and without really thinking about it find myself using more efficient editing techniques.

You listen to other people waaay too much. Just use for movement whatever keys you like best, and leave other keys alone. Remapping hjkl keys is somewhat troublesome, and best not done, because they're hardcoded in vim due to historical reasons.
