I sometimes “forget” about God, how can I stop doing that?

I feel like such a bad person for being this way and writing this, I’m not a very religious person but still, it matters to me.

How can I think about/remember him more often? there are days I can just do every day things and not even think about him once, it concerns me and I really don’t like it,

I don’t want to use some reminder on my phone or something, that’s just silly.

Thank you.
