Is it ok to not believe in any god/gods or should one keep trying harder?

To believe, or not believe something doesn't fall into the category of "wrong or right" that I can see.  People believe something because they have evidence or the argument seems logical, or they don't believe because of contrary evidence or argument.

I'm not sure what you mean by asking if it's 'ok'. Ok with whom? Ok in what way? If you don't believe in any gods, then you don't. Simple as that. I don't know who it has to be ok with. 

You can only believe what you know to be true. You cannot believe what you do not believe.

It is ok to realize that gods are human ideas and can be traced back to the cultures that invented them.

How much actual choice does one have over that?

Drawn to, not drawn to?

Can't see trying working.

I think it's about finding an answer you're satisfied with. If the answer isn't satisfying, then the search probably isn't over.

It's perfectly okay to not believe in god since he doesn't exist.

Try harder, meaning better brainwashing?

Of course it's fine.  Why would anyone want to believe in any gods?

I have met Yeshua ("Jesus") a number of times over the past 25 years. He is real, He is alive, He has spoken to me, and I have spoken to Him. Each encounter was unexpected and unique. Search YouTube for "Jesus encounter" and you will see He has appeared to atheists, Jews, Muslims, etc...

Joh 8:23-24 Yeshua said to them, “You are from below; I am from above. You are of this world; I am not of this world. I told you that you would die in your sins, for unless you believe that I am he [the messiah] you will die in your sins.”

Mat 10:37-38 [Yeshua speaking] Whoever loves father or mother more than me is not worthy of me, and whoever loves son or daughter more than me is not worthy of me. And whoever does not take his cross and follow me is not worthy of me.

Is Yeshua ("Jesus") the most important thing in your life? How much time do you spend with Him every day? Is He your friend?

Spend time every day singing (out loud) praise and worship songs... these songs should mention the blood of Jesus, the cross, and/or attributes of the character and nature of God. Here are a few of my favorites (you can set it to shuffle play so they play in random order):

Spend time in prayer every day (praying out loud). Here are prayers I say every day. Modify them as you see fit for your situation and circumstances:

Spend time every day reading your Bible (reading out loud). I use the E.S.V. but the King James (not the "New" King James) is the most accurate translation as it is the ONLY translation that uses the Textus Receptus manuscripts.

Praying in tongues is probably the most important thing I have learned to do. Learn to pray in tongues, and pray in tongues for at least an hour every evening before going to bed. Since I started doing this I have had numerous dreams, visions, and even encounters with Yeshua. Here is a document I put together to help people understand and get started:

Here is some "soaking" music to listen to while praying or reading - it is important to pray and read out loud, there is power in the spoken word:

Then give it back to Breakthrough and ask your own.
