Starter problems?

[JordanK20]

Hello I need a little help. My truck isnt starting right now. When I turn the key I get just one single click and thats it.

I noticed once a month it does this but I'll come back to it in like hour or keep playing with it and it turns over and starts. I waited all day and it still isnt starting now.

My friend told me to hit the starter with a hammer should I really do that? I dont see how it would help.

Thanks in advance
