If you're not planning on going full aggro and taking on a real player's base, try fighting some random sea monsters. Only take on what you can really defeat though! Defeating a sea monster will provide you decent rewards, like gold, experience, and resources. Your ship will take damage afterwards though so make sure to repair your ships in between trips. Your ships need time to travel to their target and back to base, so send them out before you do anything else. Consider them another part of your "queue", so don't forget about your ships!

In-Game queues
You have several different queues that you'll need to keep track of. The first and most obvious one is your building queue. You can have up to two buildings being worked on at a time, whether they're being built for the first time or getting upgraded. The second queue is your research queue. Research grants you passive bonuses to a variety of aspects about your base, so you should research as much as you can. You can have one research in progress at a time. The third queue is your Barracks. The barracks is where your troops are stored and trained. The more troops you have on your ships, the better your chances. You'll want to have as many troops as you can on hand, as they take quite a time to train.
Using Gold
The queue times can get crazy long in this game, so don't be afraid to use your gold to speed up some timers. You'll also have plenty of speed up items to fall back on, but should you opt to use gold, don't feel too bad! Gold, the premium currency of this game, is pretty easy to come by assuming you're completing as many quests as you can, especially the Challenge quests.
