You can't really receive meaningful financial advice without taking position on the following:
1) Are you comfortable committing to a lifetime of working?
2) Is there reasonable scope for a high risk high reward venture? Eg, entrepreneurship, acting.
3) Do you determine your personal comfort in terms of how other people perceive it (expensive & common option), or do you use your own metrics?
4) What is your personal understanding of retirement?
Without that orientation, there isn't really a generic position to take on debt (it might be good or bad). There isn't a generic position on investments (might be good or bad). If someone is really being taken to the cleaners maybe there is a quick change to be made, but really "personal finance" is more about expectations and habits than knowledge ad howto guides.
The fundamentals of personal finance intuitively easy to grasp, to the point of absurdity - if you consistently spend more than you earn, you will run out of money. End of the story. If you spend a lot less (10-20% of your earnings go into savings), you will weather surprises easily. If you earn a stupid amount less (40%+ pre-tax earnings saved) you will have a very easy later life.
That all only scratches the surface of orienting a strategy, let alone the details of how the myriad investment options and retirement mechanisms work.
