Someone once said;
" there are only two types of people in this world-
The first group are ignorant, the second are stupid-
Ignorant we all are, well the first group.
We try something it doesn't work we learn we try something else until we find what works through trial and error, experience.
The second group of stupid people will never learn, stuck in their own little world.
There is no hope for these people it's genetic.
The only way to deal with these people is violence, beat the shit out of them and walk away.
You might not make a change...but damn you will feel good and that person will at least think before saying something stupid."
One of the most troublesome obstacles standing in the way of any meaningful purpose of learning is quite simple.
Fear...a fear of appearing stupid, dumb.
Which is a huge mistake in itself, this saying applies most aptly.
"Don't just stand there, do something."
