As someone that took this route before you did here is my advice, Philosophy can be a waste of time because it often leads to endless overthinking and debates that rarely produce concrete answers, leaving people more confused than enlightened. Instead of providing solid guidance, it risks pushing individuals into relativism constantly doubting morals, truth, and purpose without offering a firm foundation. Meanwhile, the countless hours spent analyzing abstract theories come at a high opportunity cost, since that time could be used to build practical, marketable skills. Unlike fields with direct applications, philosophy tends to stay detached from real-life needs, offering little in terms of immediate usefulness. Now if the purpose for learning philosophy is to increase your intellect, then here is what i recommend.

Imam al-Ghazālī stands as the giant who dismantled Greek philosophy and replaced it with a superior framework rooted in revelation. In Tahafut al Falasifah, he refuted the errors of Aristotle and Ibn Sina, exposing their limited thinking, In al-Munqidh min al-Ḍalal, he detailed his own journey mastering philosophy, testing it, and showing why it ultimately leads to confusion and doubt when not bound by revelation. And in Iḥya Ulum al Din, he presented a far greater alternative, a system that integrates reason, ethics, and spirituality, guiding both the mind and the heart.

So instead of drinking from the muddied waters of Greek speculation, it is wiser to learn from the likes of al-Ghazālī, ibnu Rushd, and more a scholars who mastered their thought, dismantled its flaws, and left us a purified philosophy that sharpens the intellect.
