Those of us that have been around here a while have made our mistakes and learned through trial and much error what many new users are just discovering.
In July last year when my vote was suddenly worth a couple of $ after being just worth 0.00 the first thing I did was spam votes everywhere... back than that wasn't so irresponsible because we had 40 max votes a day.
Now its different, we only have 10 max votes per day.
They can be found by dropping down the hamburger menu.
or just go too http://steemtools.com/
There are many many steemit apps to explore.

Or you could just have fun and enjoy voting without too much thought and when you see it isn't giving that much by way of rewards, take a break for a couple of hours.
These are not written into the software but its common etiquette.
We can just vote for what we like... when we like... and that is fine too... that's one strategy and one of the least complicated.
vote for your own posts, that cool.
vote for your friends and people you follow, that's cool.
vote for strangers and new users, that's cool.
vote for content you like, that's cool.
vote for comments, that's cool.
vote up your comments, a little, to give them visibility, that's cool.
vote only for your own comments, that's not cool
Make friends, have fun and if you want more influence and a more powerful vote... buy steem and power up.
Since its now linear, if you want to hand out $10 a shot that would take around 10 000 SP
