Yikes.
To gain some experience so you don’t always lose that battleship immediately. Then you don’t stick yourself into a grind-lose in one day-grind cycle.
You don’t want to be like the many who make the mistake of rushing to fly bigger ships before they can handle them:
You really need to turn your focus in this game from making ISK to your own enjoyment. Players in EvE enjoy many different things, but whatever you do, do because you will enjoy it not just to watch a number in a virtual wallet get bigger.
Many in EvE choose to fly mostly smaller ships such as frigates even though they have been playing for years and could fly other things easily simply because they find it fun for them. A ship is nothing more than a tool for a purpose. A player could decide their purpose they want to do is best done with a titan or a frigate, but enjoyment is the purpose.
Join a group. Learn the game. Then you can decide what you want to do having armed yourself with how to play and you will perhaps give yourself time to see the many things that can be done in this game.
