... helped Edison persevere vs helped Edison to persevere

Hi,

His attitude of seeing failure as a learning experience helped Thomas Edison persevere. Could I know if that sentence is fine? Could I also say “His attitude of seeing failure as a learning experience helped Thomas Edison to persevere”?

Thanks in advance. Cheerio

Yes, they are both OK.

Hi Dozy, thank you.

I think you should talk to him one on one before you conclude.His perseverance could be as a result of a factor not known to you but cogent.

Talk to whom one on one?
I hope you were not referring to Thomas Edison.
