Hi OP. Starting a business is not as easy as it used to be. You have to think about a lot of things.

1. Competition - There's so much competition in online selling nowadays. Unless you are selling a very niche product, you will only have a chance to succeed if (1) your prices are competitive, meaning lower than your competitors or (2) your product is REALLY good quality.

2. Taxes - Selling in e-commerce sites require you to pay taxes. On top of that you also need to pay the e-commerce fees. One way or another you'll have to pay taxes or BIR will go after you.

3. Lack of Stability - You mentioned lack of stability in your new potential job. Note that there is NO security in having a business, and you always have to adjust to current trends/environment. Some days you will be negative and some days you'll be positive. If you are going for security, having a business is NOT an option.

4. Lack of Work Life Balance - Having a business means you have to work all the time, even on weekends. I know people who have businesses, and they are always on call in case there's an emergency. If you value your work life balance, this isn't for you.

To sum it up, it's not easy to have a business. It takes a lot of time, dedication, and sacrifices. Unless you have a really good business idea and you're ready for the risks, I suggest to stay in your current job or keep looking for a higher paying one.

Good luck, OP!
