How can we make up our minds to lose weight and stick to it?

If you want to make up your mind to lose weight, you must persevere, you must have a strong will, you must not give up easily, you must have a persistent heart, so that you can persist.

I was very fat at first, so I made up my mind to lose weight, but I didn't stick to it many times, which led to worse and worse physical fitness. I am cruel to make up my mind to lose weight, because I must not give up easily, I want to be better, and I want to be the focus of attention. Finally, I persisted.
