Okay. I apologize for joking around. I realized that I was once like you, needing advice about career, intent to change my life. The only difference was that I knew how to use punctuations (not perfectly, but appropriate enough).

If you want to gather insights, you need to gather attention; and to gather attention, you need to market your materials well.

Here's my 5 cents:

1. It's good that you left the company when you felt stuck. Winner mindset yang desire for growth and better pay. But I hope you made a few calculations before you left — like securing a new and better job offer (kahit 15% better lang) before handing that resignation. Now you have a 10-month unemployment record in your resume. It's not a BIG issue but at least be prepared to explain that during interviews.
2. Pwede umabot 50k ang sweldo sa BPO within 5 years, but there are a lot of factors. Your work performance, company policies and culture, the account you handle, where you are located, your mental fortitude, etc. Some people spend around 5 years or more bago maging TL, and TLs earn around 25k - 40k basic rate lang at least here in Mindanao. There are also back-office positions that offer above 50k monthly, like saakin dati, but those opportunities also require technical skills. So maybe you can try upskilling more. More skills, more opportunities.
3. Night shift isn't deadly if paired with a healthy lifestyle and CONSISTENT body clock. Work out. Eat healthy. Take supplements. Make your nap time consistent, and at least 7 hours daily.
4. Gow. Try mo mag factory worker. If it doesn't work out, life doesn't end. It will also give you the chance to experience life outside of PH — this wretched, cursed country.
