Because whether it is running or other sports or work, as long as you reach the limit of your ability, you will feel bored or even annoyed, and this is the time to test a person's endurance and accomplishment.
If you can persist today after running tired, even for a while, then you have surpassed yourself to some extent. Isn't the meaning of life to constantly surpass yourself and make yourself stronger?
I suggest that you can set yourself a goal every day, and you must ask yourself not to stop until you reach it. This is to exercise your endurance.
For example, if you run three kilometers every day now, you will feel tired and tired. Then you can set yourself a goal of five kilometers.
Yes, you just have to go beyond your limit, because the more tired you are, the more lazy you will become, so when you encounter other things in the future, you will have no determination and perseverance to persist, and it is easy to fail.
If I can finish the goal of five kilometers the next day and feel a little tired on the way, I finally stick to it.
That means you are great, at least you can basically overcome this boredom. I believe that if you still have this perseverance the next day, you will not necessarily feel tired and bored.
Come on, it takes time and persistence to form good habits.
