If you're bored
or sad, it can help to remind yourself of all the things that have been
developed/invented in your lifetime which you've gotten so immersed in that you
wonder how you possibly could have ever gone without. Think of how many more
will come to exist in your future, and then you will look forward to things
you're not even aware of yet. The best part of that is you don't miss those
aspects or agonize over not having them, since you don't yet know what they
are--you just know they'll be a great surprise. And if you can imagine them,
you can make them.
