Correctly understand yourself and take corresponding actions based on your strengths and weaknesses.

Some things will definitely get better as long as you persist in doing them.
But not everyone will stick with it.
There are many ways to endure hardship, not necessarily through hard labor or by not eating.
Stick to getting up early, stick to your routine, stick to exercising....
I hope to work harder in the future.
Really willing to take action for the life you want.
