I am shallow in nature and wisdom, and I often have troubles in my life. How can a person without wisdom live correctly, happily and comfortably?

Some wisdom is acquired. The key is to clear your mind and don't entangle things unnecessarily. Your lack of practicality and enrichment shows that you are demanding of yourself, but you are afraid that you can't do it, so it is easy to get upset. I suggest you make a moderate request for yourself. The most important thing is to learn to know and appreciate yourself. Learn to set effective and achievable goals, and then step by step.

Anger, learn to tolerate, learn to empathize, and don't look at things with a one-sided eye. Think more about something.
