Hello, as here is the biggest community of QA on internet i would like to get some advices from you.

First of all i would like to tell you that i am QA Manual Tester but only on Mobile Games. Well i think that now it's time for me to move on and i would like to switch my career on software testing.

Here is the big problem, i don't know what should i lead. Some of my ex colleagues told me that i should learn some programming, thats why i've started to learn frontend programming ( CSS3, HTML5 and Javascript ) , the rest of them told me to try to learn theory that is present in the ISTQB foundation syllabus.

I would be verry happy if you will tell me what i sould learn and maybe some useful tools.
