Read as much as you want all the time. Read exactly what you want, no matter whether someone else might think it's not "worthy" somehow. Who cares what anyone else thinks? Feed your brain what it loves.
Second, write something every day. Whether it's writing in a journal or writing poetry or songs or scenes from a story you're working on, keep that writing muscle in your brain exercised and limber. It's hard to get started on something when you haven't written in a while. If you make writing part of your day every day, you won't be so nervous about writing something new.
And third, do something interesting in your life every day. Learn something new. Talk to someone new. Make new discoveries. You'll have more to write about if you're actually living your life and not just reading about other people's. Go be interesting and then tell us about it.
