Besides beambot's excellent observation ... do the best you can. In recognition of your inexperience, don't hold your opinions too strongly, and don't be disappointed if you decide you're working on something that doesn't matter. Everything you do gives you more understanding.

As you consider what you're doing through the years, consider what matters to you, your employer, their customers and users, and society. You may or may not be able to satisfy all of them, but they're all interested stakeholders.

What matters to you should come first, because you may not give something the effort it deserves if it doesn't matter to you.

Now that sounds like a problem that matters. :)
