If you're interested at all, why don't you give it a try?
You should try it even if you think you're just a little interested.
ーIf you're interested at all, why don't you give it a try?
「少しでも興味があれば、それをやってみたらどう?」
at all で「少しでも」
to give it a try で「やってみる」
ーYou should try it even if you think you're just a little interested.
「少しだけしか興味がなくてもやってみなよ」=「少しでも興味があればやってみるべきだよ」
