30 years old and needing direction.

Answer 1

There is nothing to worry. Just try to understand what you want, in which field you are interested and then try your best to achieve your goal.

Answer 2

Don't worry about it or stress too much, I think that makes it worse!

Still not being sure on your lifes direction around the 30 mark is more common nowadays than you think, in the west at least.
Just be positive and enjoy your life, that's all that is important.
