The Four Species and the Concern of Pride

To the esteemed Rabbi of Israel, our great Gaon, Rabbi Amram Fried, shlita. May I ask a question: I am a simple and young avrech, and I have no extra money at all, but I strive throughout the year to save money for the Four Species. Thank God, I manage to buy very beautiful Four Species every year, especially etrogim of all the prestigious varieties, and this costs more than 10,000 shekels. Now the question arises: On one hand, the holy books contain great warnings not to take pride in the etrog, especially when it comes to the most beautiful etrogim that can cause great admiration among people. Therefore, it would seem preferable to take the Four Species at home, so no one sees them, and there is no concern of pride and arrogance. On the other hand, there may be a matter of enabling many others to fulfill the mitzvah, allowing other Jews to bless and take the Four Species with great beauty, rather than keeping the mitzvah only for myself. Therefore, perhaps it is better to bring them to the Beit Midrash. Therefore, my soul is in question, should I come to the Beit Midrash with the Four Species or not? P.S. In most years, I did not come to the Beit Midrash with the Four Species [for the above reason, and perhaps also due to laziness]. Last year, I did bring them to the Beit Midrash, and dozens of Jews waved them. This year, I did not bring them to the Beit Midrash again. I would be happy to know what the true Torah opinion is, what is the correct conduct to follow, so I know the path to take in the coming years, with God's help. Thank you very much Have a healthy winter

If there is no intention to boast, it is correct to bring
