Y Combinator
“the vast, vast, vast, vast, vast majority of successful founders that we funded at YC have effectively no presence whatsoever, especially not in the early stages, right, especially not in the first five or six years of the lifetime of their company, and that kind of exposing yourself to all that noise or putting a lot of energy into establishing thought leadership can be a huge distraction from doing what really matters, of making your company work.”

用法說明
How is "Energy" different from similar structures?What usage mistakes are common with "Energy"?
energy to do vs energy for doing
- energy to do 強調「有足夠的精力去『完成』某個具體動作或任務」。這裡的
to do是不定詞，帶有目的性。 - energy for doing 則強調「有精力去『從事』某種活動或狀態」。這裡的
for doing中的動名詞 (doing) 更偏向描述活動本身。 - 在否定句或疑問句中（如
don't have the energy to...），使用 energy to do 更為常見。 - 當談論進行某項活動所需的「精力類型」或「精力來源」時，會使用 energy for (something)，例如
food provides energy for running。 EN: After work, I don't have the energy to cook a big meal. 翻譯: 下班後，我沒有精力去做一頓大餐。
EN:After work, I don't have the energy for cooking big meals.
翻譯:下班後，我沒有精力從事烹飪大餐這類活動。
EN:She saved her energy to finish the marathon.
翻譯:她保存體力是為了要跑完馬拉松。
EN:Children seem to have endless energy for playing.
翻譯:小孩子似乎有用不完的精力可以玩耍。
總結建議
一般情況下，表示「有/沒有精力去做某事」時，使用 energy to do 是最安全且最常見的選擇。

常見錯誤
What are common mistakes with "Energy"?Which "Energy" sentences look correct but are wrong?
×I have many energies to finish this project.
✓I have a lot of energy to finish this project.
"Energy" is usually an uncountable noun when referring to physical or mental vigor. Use "much", "a lot of", or "little" instead of "many".
×This battery has a high energy.
✓This battery has a high energy capacity. / This battery is powerful.
"Energy" refers to the capacity to do work, while "power" is the rate at which energy is used or transferred. "High energy" typically describes a person's state, not an object's capability.
×He put all energy into his work.
✓He put all his energy into his work.
When "energy" is modified by a possessive (his, her, my, their) or a determiner like "the", it usually requires that determiner. "All energy" is too vague; "all his energy" is specific.
×I need to save my energies for the marathon.
✓I need to save my energy for the marathon.
The plural form "energies" is rarely used in modern English for physical stamina. It is sometimes used in literary or formal contexts to mean "efforts" or "resources directed toward a goal." For physical/mental vigor, use the uncountable "energy."
×I don't have the energy to lift this heavy box.
✓I don't have the strength to lift this heavy box.
While related, "energy" is about the capacity for activity or vitality, and "strength" is about physical power or muscle force. For a specific physical act requiring power, "strength" is often more accurate.
×This food makes energy for your body.
✓This food provides energy for your body. / This food gives you energy.
The common collocation for food/fuel is to "provide", "give", or "supply" energy. "Make energy" sounds like the food itself is manufacturing energy, which is not the standard expression.
