I am 30 years old and I still don't know what I want to do in life or career?
Life: Live as a parent or make a family or adopt a child and let a sense of responsibility flow through your mind to help you understand your goals and your purposes.
Career: If you have finished your education and graduated, then you can earn a diploma or graduation degree to enter a job.
What if you don’t have any?
Establish an organization or work in groups with no requirements. If that doesn’t suit you as well, then start your career in media as a freelancer and learn about micro transactions, IT technician, and finally grow expertise. You can also plan for your pension if you are still a student (depending on your country’s regulations and if you can still be an academic student as sometimes age doesn’t matter according to the region you reside in) and direct your finances to investments like opening bank accounts, whether local or online, and then start your trades. Trading is the best measure for students.
