I can't go back to anything else after using GPT PRO

At first, I used the free version,
then I switched to PLUS to get more in-depth answers,
and then I switched to PRO to help with my work.
No matter how I look at it, spending 150,000 KRW felt like a waste, so I switched back to PLUS,
but the response speed was slow and the capacity was too small,
so I ended up paying for the 150,000 KRW PRO version again after just two days.
It feels a bit wasteful,
but since GPT is now essential not only for daily life but also for work, I'm planning to keep the PRO subscription as a must, even if I have to cut back on other things. haha
