Trouble with the meaning of きっかけ in a sentence


The sentence is the following.

> きっかけはほんの些細なことだとしても。それが、未来の大きな流れを決定づけてしまうこともある。

(I'm not really sure if the first period is supposed to be there, but the
narrator took a relatively [long pause](https://youtu.be/vdsNfdWirtk?t=25
"Source") after としても)

The provided English is the following.

> No matter how trivial something may seem, It has the potential to shape the
> future.

I get the gist of the sentence, also thanks to the english version, but I am a
bit troubled by the specific meaning of the first part. My two possible
interpretations are something on the lines of

> Even if something is (seems) really trivial in the beginning, it can shape
> the future later on.

and

> Even if the origin/cause of something is really trivial, this something can
> shape the future.

I have and will try and familiarize more with the word きっかけ but in the
meantime I wish I could get some help with it in this context.

Thank you very much.




The best English word that describes きっかけ is **opportunity**.  
Following that opportunity is **the beginning of something**.

A common question asked during interviews :

> Q : 日本に来たきっかけは何ですか？  
>  A : ネットで日本の文化についての動画を見ました。それがきっかけで日本に対する興味が湧いてきて。。。

The interviewer asked what is the **opportunity** that caused you to come to
Japan. You answer that it's this one video you saw in the internet. Since then
you've **started** to develop an interest in Japan's culture and from there
you **started** to study Japanese, etc.

To make it easier to understand your sentence above, think of one small match.
It seems trivial at first, but when you light it up and throw it into a
gasoline doused house, it has the power to completely annihilate that house
into ashes. The residents would have to sleep on the streets, etc. Likewise
you can just choose to not use the match, and the house would be fine.
