Brother, improving the content is not a short-term matter. Supplementing knowledge and increasing experience are all good ways.

Teach you a few ways to make others look meaningful immediately: speak less. Silence can sometimes give people a deep and restrained feeling. Gaze, please note: Gaze can betray a person’s heart, but it can also be hidden. Therefore, don’t keep your eyes fixed on one point for a long time, and don’t be dull. Rather, it should float, wander, and seem incomprehensible. In short, a silent expression + blurred eyes = a person with a rich heart.

If you do the above, you will basically be a very meaningful person in the eyes of others. Finally, remember, smile, don’t laugh! That way, you'll be invincible. (I deceived girls like this in college and got excellent grades!)

Of course, if you pretend, you can only do it for a while, so you should improve yourself quickly.
