Guidance

[zara]

Salam all,

From my understanding of the Quran,God chooses who He guides.Are there specific things we as humans need to do to earn said guidance?

Secondly,when you observe children,you notice that some are more compassionate,caring,aggressive,helpful etc than others.If some people are born with an advantage over others in their character,should they then be judged differently,and is there anything that predetermines what kind of person we are born into?

Thanks.
