Hi, newbie here. Just want to ask about what are the things I need to be looking at given my scenario:

1. mid 20s
2. just bought Public's Regular Savings Fund
3. looking to add on to the portfolio
4. goal of earning extra income

I know these questions of 'what-to-do' get asked around a lot, but I'm more interested in learning how to be self-reliant and have good knowledge to make own decisions. Thanks all!
