Financial planning

My parents, they are not concentrating in financial planning of family education since long time ago. Cause by their busy works when i'm still a teenager, my sense of financial planning had been very bad. I spent most of my pocket money to buy things and barely save any money.
Time to grow up. Gotta buy things accordingly and do proper savings. Investment wasn't my best field, unlike bor. My boyfriend asked me to buy an accident insurance myself, who knows what happen in future.
Thinking of ways to earn side income and grow my savings.

Why money makes human failed so desperately.
