Words come and go, but actions can't never be erased. People prefer to remember actions, even if its so little that you need a magnifier to see it. Words have also an influence on people, but actions talk louder and harder.
I don't say, we must stop talking from now on and make use of hand signs. We must plan and start focusing on practice more and less talk. Turn words into actions. Practice what you say.
A good example of just talking and not practice that much is what I'm doing right now. I must write something about this matter and it must be more than 200 words. I practice a little at least. But can you benefit from what I'm saying?
To talk a lot you can't gain experience, only when you're learning a new language. But to practice a little means much more than just talk a lot. Actions are more powerful than words. People act on actions. We can learn from words, but a few words can also means a lot. To many words can be to many information. We must start focusing on the little practice and with a little practice on the little practice, we will maybe talk less and do more.
