在练习过程中，反手反撕的问题仍然比较突出：摩擦过多而撞击不足，摩擦太薄导致容易下网或出界，拍面击球点位置偏低，重心偏高

正手拉球基本稳定，发力可以拉出质量很高的球。未来需要逐渐将动作幅度变小，用尽可能小的动作打出尽可能高质量的球，还有注意快速还原、长短变化和节奏变化

If you think so much about what you want, even if it’s out of pocket, you’ll eventually reach it and you won’t even realize it.

之前偶然尝试了正手徒手训练的妙用。通过最近几次训练，我来总结一下正手徒手训练的要领

最近两次训练开始使用反手拉球，在本文中我同样会进行一些技术要领和现存问题的总结

这一天晚上训练内容和平时基本差不多

1. 正手近台攻球
2. 正手中远台拉球
3. 反手近台反撕
4. 发下旋球，搓球，正手起下旋衔接正手连续拉球

但是今晚进入状态非常之快，正手连续拉球质量很高，而且手感球比较多；反手相对差一点，一开始感觉不太能够控制得住球

不论什么时候，永远要将这几个词牢记在心里，在训练和实战中贯彻落实：步伐，重心，腰胯，动作小巧紧凑，发力集中

写在前面

刑法学中有一个很重要的概念叫法益。法益法益，即一切法律所要保护的利益。在入罪层面上必须考虑行为是否侵犯了法益，如果一个行为没有侵犯法益，那么自然不构成犯罪。

具体到某件物品来讲，对象 A 对于这个物品拥有那些权利，法律是否保护这些权利不受侵犯，而一旦另一个对象 B 侵犯了 A 侵犯的某种权利，将会受到什么惩处。

搞清楚对象对物品拥有的权利，将有助于我们搞清楚某项罪名是否成立。

现存问题

结合 2023 年 2 月 24 日的乒乓球训练情况，我针对正手和反手两个方面，总结了当下打球时存在的主要问题，

正手

1. 刚开始时正手拉球节奏越来越快
2. 向上发力过多，虽然更好的保证了球的稳定性，但是球不够冲，质量不高
3. 手上参与绝大部分的发力，而身体和右腿的参与较少发力
4. 正手前后步伐很不协调

反手

1. 反手握拍吊腕而且内扣，导致发力直上直下，动作僵硬别扭
2. 反手撕动作幅度太大，稳定性不高
3. 反手位短球处理稍有进步，但是有时候意识还不到位，仍需加强

Overview

Green energy | Plug and Pay

The decarbonize faster, let renewables firms make money

Amid the misery war in Ukraine and the global energy crisis, there is a glimmer of good news. The green transition has speeded up. True, a spike in natural-gas prices fueled greater demand for coal, the dirtiest fossil fuels. But it also led consumers to use energy more efficiently. And, more significantly, it spurred investment in renewables around the world. As a happy consequences, the green transition may have accelerated by five to ten years. Yet the remarkable thing is that the transition could have proceeded at a faster pace still. Even as the governments have loosen purse-strings, they have begun to blunt the incentives to invest. One problem is obtaining permits. Endless delays stop firms that want to invest from breaking ground. (Denmark stopped processing all applications for projects like offshore wind, after a dawning realization that it may be in breach of EU law.) The gains from cutting red tape are large. The bigger problem is that some renewables providers are now rethinking their investments altogether, because energy projects are becoming less attractive as price caps and various taxes (windfall tax), together with rising costs, are pulling them off. Bloated costs, pushed up by post-lockdown rebounds and war-induced disruptions, would be manageable if they could be passed on. But the governments are increasingly micromanaging power markers to keep prices low, or to raise revenue of their own. The results has been squeezed profits. The four largest Western turbine-makers are losing money and some renewable generators are struggling to make money. This is clogging up project pipelines. Governments are keen to keep power prices low today, but that may be a false economy if it reduces the renewables spending needed for tomorrow. All this means that, if investing is to stay attractive, green power will need to be sold at higher prices than governments would like. If the energy transition is to happen fast, there must not be a race to the bottom.

透过经济学人笔记的演变讨论从简单到复杂、逐步优化方法的妙用。

好吧，上一句话写得有点唬人，其实我只是想记录一下自己的经济学人笔记模板的版本更新日志。

THE FUNDEMANTALS: Why Tiny Changes Make a Big Difference

The surprising power of atomic habits

It is so easy to overestimate the importance of one defining moment and underestimate the value of making small improvements on a daily basis.

Habits are the compounding interest of self-improvement.

Your outcomes are a lagging measure of your habits.

Breakthrough moments are often the result of many previous actions, which build up the potential required to unleash a major change. Similarly, habits often appear to make no difference until you cross a critical threshold and unlock a new level of performance, which can be a great challenge to your patience.

你得到的结果是衡量你习惯的滞后指标。

有一句话是这么说的：你的现在是由你的过去决定的，你的未来是由你现在所决定的）

好习惯是自我提高的复利。

你在培养习惯的过程中，有相当长时间是感受不到它的影响的，直到有一天，你突破了临界点，跨入了新境界，这很考验一个人的耐心。

忘记目标，专注于体系。目标是关于你想要达到的结果，而体系是涉及导致这些结果的过程。
