Daily Q&A session for private messages: Career Growth and Planning

If it were me,
I would first think clearly about the "main purpose" of this money.
You're currently in the second year of high school,
and time is actually your biggest advantage.
If buying a computer is for seriously studying AI, programming, and working on projects,
rather than just entertainment,
then the computer is more like a "tool to enhance your skills,"
and the long-term return might be higher than simply leaving the money idle.
Starting to accumulate skills and projects early
will help with future college choices, internships, and even earning ability.
But the prerequisite is that you truly commit to continuous learning,
not just a fleeting interest.
If you're just somewhat interested,
you can try using your current device or a cheaper option first,
to see if you can stick with it before upgrading.
As for investing in US stocks at 18, there's no rush.
The most important aspects of investing are the source of capital and your understanding.
Focusing on improving your skills now,
will enable you to earn more in the future,
making it easier to succeed in investments.
