The best thing about writing:
The entry bar is pretty low.
All you need is a pen and some paper. As for writer’s block? As far as I can tell it doesn’t apply to letter writing. I get it: sometimes on certain topics writer’s sometimes hit a snag, or a wall, or the end of cliff – whatever you want to call it. But writing a letter to yourself or really anybody else it’s just about talking or writing about whatever comes to mind. In that sense, there is always a path around the block. In that way, maybe what’s not written about is more interesting that the words that are actually put down.
My point?
If you’re bored, pick up and pen and start writing. I highly doubt that you’ll get more bored by doing so, and more than likely you’ll get a “big kick” and great exercise jumping over all the so-called writer’s blocks.
