I am more active now compared to my first weeks on the platform. When we are new, we are only delegated a little Steem Power which can only be used for little transactions also. Also, we don't get yet curation rewards so taking your time upvoting posts does not do you a favor.
However, just recently, I have spare amount in my blockchain wallet so I bought a delegation at @blocktrades. It is not huge but my resource credits is more than enough for me to stay here for 8 hours in a day. I usually spend that 8 hours making posts, commenting which I cannot do when I still have a very meager resource credits and upvoting.
