Agree with segamatboy.

Nak buat, then buat aje lah.

Only yourself will know the real reason for emigrating. There's nothing wrong if you want to earn more money or just want a life somewhere where no one cares about you.

It's not compulsory that you mix with the locals though doing so would make your life easier. If you're an introvert and prefer to stick to your old friends, then emigration will be a great challenge for you. If you're one who enjoys meeting people, building relationships, can get along with everybody then emigration will be an exciting opportunity for you.

Emigration after all means leaving your comfort zone, leaving familiarity and transplanting yourself abruptly into a foreign environment. The weather would be harsh, food will be different, language and popular culture will be different, your lifestyle will have to change. No mamak, no hawker store, no 24 hr shops, no pasar malam. If you can't make friends easily, you'll quickly get depressed.
