Bạn đang từ thiện bao nhiêu khi mua tờ vé số 10k?


Cứ ngồi trong quán ăn, quán cà phê là ai ai cũng thấy người bán vé số. Vấn đề tâm lí ở đây là phần lớn người bán vé số là người già và em nhỏ.

Câu hỏi được đặt ra ở đây là: Mua vé số có phải là làm từ thiện không?

Khi bán 1 vé 10k, số tiền bán được được phân bổ xấp xỉ như sau:

  • 1k – 1.5k: người bán [1]
  • Phần còn lại (8.5k – 9k): dùng để trả cho người trúng giải, nộp thuế và chia cho các đại lí.

Cụ thể, số tiền trúng giải chiếm khoảng 50% tổng số tiền vé bán được [2], nộp thuế nhà nước khoảng 20% – 30% tổng doanh thu [3]. Số % còn lại thuộc về đại lí và người bán.

Như vậy, trên góc độ “từ thiện”, mua một vé số 10k thì chúng ta đang “từ thiện” trên 2 góc độ:

  • Cho người bán 1k – 1.5k
  • Đóng góp chung cho xã hội: 2k – 3k; vì tiền thuế thu từ vé số được quy định (trên lí thuyết) dùng để xây dựng các công trình công cộng, giáo dục, y tế, …

Như vậy, nếu qua việc mua vé số bạn muốn “cho tiền” cụ già bán vé thì có lẽ không mua vé mà cho cụ 2k thì tốt hơn:

  • Bạn từ thiện cho cụ được nhiều hơn khi bạn mua vé số (2k > 1.5k)
  • Vé vẫn còn đó, cụ có thể bán cho người khác
  • Bạn chỉ tiêu 2k thay vì 10k

Players vs Coaches. Researchers vs Teachers

Being a football player is not the diametrical opposite of being a football coach. Likewise, being a researcher doesn’t exclude the teaching role; more often, it entails a teaching role.

But it’s interesting to recognize also that being a player is quite different from being a coach. And what makes a good researcher is not necessarily what makes a good teacher.

Muhammad Ali: When it really counts

Muhammad Ali is one of the greatest heavy boxers in the sport’s history. 

It was told that in a conversation, the interviewer asked him: “How many sit-ups do you do?”

He answered “I don’t count my sit-ups”.

But he then elaborated: 

“I only start counting when it starts hurting. When I feel pain, that’s when I start counting, because that’s when it really counts.” 

That’s when it really counts: not the miles you’ve run or the work you’ve accomplished, but the extra miles, the extra hours, the extra work, the extra responsibility that you take, while others refuse or not motivated enough to do or take.

That’s what really matters. The extra miles, not the miles


I’ve been hearing a lot about him through the news. 

Now I know why he’s among the greatest athletes. 

Changeability and Growth

When we were a child, we grew up unconsciously – we neither resisted nor purposely accelerated the process (of course, our parents probably did the latter)


When we get older, growth now requires conscious efforts. 

And this is probably the reason behind the widespread phenomenon: the older one gets, the more one resists change. Because as we get older, our ability to adapt naturally declines.

Change is a fundamental ingredient of growth. To fear change means to stop growing, to close our mind to a finer reality and to stop getting closer to truth.

Young people, by definition of the word ‘young’, are well equipped for growth.

But why so many of them decide not to grow, by not leaving any room for change?

Free vs Cheap vs Valuable

In general, we seem to give a lot of credit to “free” stuffs.

This is obviously a mistake in our mind’s processing. Upon a closer examination, what’s important is the difference between the benefit and the price, not just the price:

Value (x) = Benefit (x) – Price (x).

Getting a free rotten tomato is not going to be valuable.
Paying 25$ to buy a book that boosts our morale or inspires us to think is indeed valuable.

No, it’s invaluable.



Free things usually cost us more in the end. Mostly because their benefits are negative. And sometimes because their actual price is > 0, which means it’s practically a loan, not a purchase.

Similarly, being cheap in terms of price is not what really matters, logically speaking. Value is.

Being a big fish

It’s good to be a big fish.

Of course, it’s the small pond that makes the fish look big. A small pond makes us believe we are quite good. And that invariably makes us feel good.


And that usually traps us into believing that we’re really….big, big even out of the context of the small pond. Absolute big.

And one day, we happen to see bigger better fish. Oh… it’s the pond(!), not the fish, that actually provides meaning for “big”.

But being used to being “big”, a terrible thing then happens: we become defensive, to keep the status quo, which has never been real – except in our mind.
