3 Key Principles for Beginner Investors: Understanding Financial Planning's Infinite Game Through Deng Kaiwei's Baseball Journey
Is your financial planning like waiting in the bullpen, not knowing when …

Many people, after receiving their paycheck, prioritize satisfying their spending needs — and by the end of the month, there’s barely anything left, making effective saving impossible. This “spend now, save later” pattern almost always leads to failed savings plans. Flipping this around to a “save first, spend later” strategy can truly change the situation.
Steps to Implement:
This approach puts saving first, ensuring you steadily accumulate funds every month. You can even become a “high-class paycheck-to-paycheck” person (月光族) — spending freely within your limits with zero guilt.

In an era of material abundance, impulse buying has become the norm. These unconsidered purchases are often the primary reason we can’t save money.
Steps to Implement:
These habits cultivate rational spending behavior and protect you from the financial pressure that comes with impulse shopping.

These tools and methods help us manage finances more effectively and achieve steady wealth accumulation. (Full disclosure: I no longer use tracking apps myself — I’ve moved to a budget-based approach and happily live as a relaxed, guilt-free spender within my limits.)
Note
Xiao Mei is a 28-year-old marketing coordinator earning NT$55,000 per month (approximately USD 1,700). For the first three years, like many young people, she spent nearly every paycheck on shopping, food, and entertainment, regularly maxing out her credit cards. By the end of each month, she was borrowing money from colleagues to get by.
Then an unexpected medical bill became her wake-up call: living without savings was simply too dangerous. She started seriously learning about personal finance and implemented the mindset shifts described above. She began with the most fundamental change — “save first, spend later” — setting aside 30% of her salary every month without exception. She then started keeping records of her spending, began researching investing, and laid out a five-year financial plan.
After two years of consistent effort, Xiao Mei had not only paid off all her credit card debt but had also built an investment portfolio of approximately NT$1,000,000 (around USD 30,000), including regular monthly contributions to ETFs (exchange-traded funds) and stocks. Today, she continues to grow in her career while generating additional income from side projects and investments. This transformation didn’t just improve her finances — it filled her with confidence about the future.
For many people, the biggest obstacle to saving is simply not knowing where their money is going — or not having a realistic sense of their actual spending capacity (a lack of budget awareness). The result? This month’s income is often being used to pay off last month’s expenses (credit card bills).
Adjusting your cash flow through systematic steps isn’t easy, because even just converting last month’s debt into a normal, current-month expenditure requires building discipline and forming new habits.
