[IWantOut] 26M Indonesia -> Netherlands/US/Japan

Hi everyone, i decide for my future to move out from indonesia to one of the country that i mentioned in the title.

i have a degree in computer science and currently working in a small consultant company. when moving out, i dont mind working in other career path to survive first.
for language, i can speak english (basic - intermediate) other than indonesia.

i targeted myself to make sure that in 2/3 years i already moved out from indonesia.
now, i have a few question that still haven't answered yet by me and i need others opinion.

1. should i go to europe/us/japan? and why? (for context, i never visited japan/us/any country in europe so i need other opinion about living in one of these country and what are the pros and cons)
2. can i apply for a job from indonesia before moving out? i just wanna make sure that if i moved out, i already have a job and i can sustained myself without asking help from my family.
3. what are the plans to make this plan a success?

Thanks in advance!
