举一反三
(2026·北京理工大附中期末)One of the most important life skills is self-discipline(自律). It helps us develop healthy living habits.
Everyone feels good when they know that they are doing good things. Probably one of the biggest problems with self-discipline is the word “discipline”. Discipline really does not have to be painful or difficult. You can start by taking small actions and only one at a time until it becomes something that really makes you feel good when you are doing it. Let us say that you want to build a good body. You do not have to go to a gym and begin a 5-day week programme. What about walking around your neighbourhood once a day for a week, and then increasing it to two times a day for two weeks?
It really starts with finding your motivation(动力). Why do you want to build a good body? Is that reason strong enough? We need to remember that we have choices and one of them is to say “no” to the things that will take our attention away from completing things to make our life happier and healthier. We have the power to say “yes” to right things, no matter how small, each day, to head us in the direction(方向) of our dreams.
We all know that when people make a plan with small, simple steps to get to the goals they have, they are more likely to achieve them. You need to listen to your heart and know what effort you want to put into it as you move towards living a better life.
You don’t need to make this hard. Just do something to head yourself in the right direction today and then do it again tomorrow and every day after that. Remember, a baby step is better than no step at all.
