Thank you. It's not an easy path, keep posting quality content, search for contests and be consistent

Does commenting and upvoting on other's posts help me grow??

you just earned some money by commenting, does this help answer your question more simply? :)

yeah, i am getting hold of it

in a sense it does, it attracts people to you and encourages them
to engage, nonsense comments probably not, but well thought out and meaningful I think it does help you grow. The more sp you have and the higher your voting power will attract more people and help you grow even more.
