Job hopping not good?

I've been in this new co for less than 3 mths. N I'm ready to quit. In fact, I've been contacted by agents, asking if I'm keen on same positions but in different industry, but with higher salary. 

Why not, right? If I'm going to be facing the same shit, I may as well get paid more for it. 

Ok, y do I wanna quit. I really don't like logistics n postal services. I took the job cos I thought since the co is so familiar n big, it won't be so tough. I've nvr been so wrong. Turns out our services are so troublesome n bad that when I do get to speak to someone, I end up being Aunt Agony. 

My mum thinks I'm gonna leave a bad record in my resume. I don't think loyalty actually pays anymore, in times like this. 

Living in Singapore is expensive. Especially when u r on long term medication. I don't need to earn a 5 figure salary. I just need to earn enough to have a comfortable life.
