20% of effort determines 80% of productivity
Remember the 10,000-hour rule to become an expert? Turns out, you only need 20% of that time to become GOOD at most things. (2000 hours, roughly 2 hours of consistent work per day for 2 years)
Let's take learning English as an example.
Grammar
English has a total of 12 tenses. But you only need to master 4 basic ones:
- Simple Present
- Simple Past
- Simple Future
- Present Perfect.
Most English conversations, articles, and papers I've come across use these tenses. You only need these 4 to pass any Speaking Test. Even a normal user can talk fluently without knowing Present Perfect and Simple Past.
Vocabulary
Simplify your vocabulary learning. Some people categorize words into 3 types:
- those for speaking (simple: do, eat, drink)
- those for writing (formal: consequently, edge technology)
- those just for exam (too difficult, specialized). No need to learn them all if you won't use them!
A tip for coders: If you're unsure which 20% of vocabulary to learn, crawl all the data (wiki, BBC articles, etc.) and learn based on frequency.
import requests
from bs4 import BeautifulSoup
from collections import Counter
import re
# Step 1: Fetch data from Wikipedia
url = "https://en.wikipedia.org/wiki/Main_Page"
response = requests.get(url)
html_data = response.text if response.status_code == 200 else None
# Step 2: Extract text from HTML
soup = BeautifulSoup(html_data, 'html.parser')
text_data = ' '.join([p.get_text() for p in soup.find_all('p')]) if html_data else None
# Step 3: Tokenize and calculate word frequencies
words = re.findall(r'\b\w+\b', text_data.lower()) if text_data else []
word_frequencies = Counter(words)
# Step 4: Select top 20% of words
total_words = len(word_frequencies)
top_words_count = int(total_words * 0.2)
top_words = dict(word_frequencies.most_common(top_words_count))
# Step 5: Display or save the list of top words
for word, frequency in top_words.items():
print(f"{word}: {frequency}")
Listening
Q: Why do I listen to English every night and still not understand anything?
A: The reason is, 80% of the time, I'm just passively listening. The best way to learn is active listening. Listen -> listen again -> read the script -> listen again. Also, learning listening skills heavily depends on how you practice pronunciation.
Listen -> listen again -> read the script -> listen again
Conclusion
Of course, this isn't a shortcut. These 2000 hours demand 100% focus. Don't let yourself be distracted by your phone or the surrounding environment. Wishing you all success!
