Does this hint have any effect? For example, I have to say it several times a day. I am healthy, I am doing well, and I am attractive. In this way, I am healthy.

Self-suggestion is a useful method.

But I don't think it's useful for you to do so.

The first thing you can say in the morning is that you are healthy, capable and attractive.

You can repeat some appropriate words when you meet something.

For example, when the boss scolds you, you say to yourself, I am very capable.

When you hint to yourself for a long time, you will involuntarily develop in that direction.

For example, when you are going to stay up late, you say to yourself, I am healthy, but at this time you will definitely think,

I am healthy, but staying up late is not good for my health!

At this time, you will feel that it is better to sleep.

Hint at yourself when you can't sleep.

In fact, this method also works.
