@
vivianalive You made a good point. Anyway it's my dad decided my way before my 20's not me, it's a good choice though. I want to live for a job not a job for live.
As for the Front-End part, I can't say I totally agree with you. It's more than books and pages.
I read your blog and decide to use English here, and I believe you have a better understanding on Front-End than me, so no more arguments on Front-End part here. Actually, I learned Finance for just 2 years, so I know nothing about Finance :( & I don't want to know.
Thank you for your advice, vivian.
