Biggest financial worry would differ from person to person, from time to time, and from age to age. A 13 year old might be more worried about where to spend his money while a 31 year old would be more worried about how much he can save.
General financial worries include: how to pay off debt, how to save money for college and school, how to invest money and where.
The solution would be to save money instead of having to take a loan from the bank, which will increase your debt. With proper planning one can avoid debt, if they plan for the future. Investment is something that should be studied and people would need to educate themselves about the market and investing. To save money for college and school, again proper financial planning is required and timely planning as well. One should plan years and months ahead of time when it comes to finance so that they don’t have to suffer from issues like debt and school or college fees.
