City Hall across the pond and a question About upvoting

This is looking across our Pond called the Duck Pond across at our City Hall Unfortunatly with wires and vegetation in the pond you don't get a good reflection looking across this way

Still working my way around on this site and one thing it seems the more I read about the more confused I get which is upvoting and how many you should limit yourself to a day

I have seen a few who say only do up to 10 a day so you keep you upvoting power above 80%

I saw a couple of posts yesterday saying you can do 40 a day

And then others who say when your just starting like me your upvote is just slightly better than worthless so use it as much as you want and do not worry about it

Up till now I have been trying the first option but really am now wondering what others are doing or advising

Cheers
