I'm not sure how to start this

A couple of years ago, I tried blogging. I only posted three times. I also tried vlogging but only posted a couple of videos. The most popular one was a camping trip to RimRock Lake. I would have liked to do more blogs or vlogs but I wasn't sure what to do. To be honest, I still don't know but I'm starting to think this is more for me. I want to be able to write about whatever is on my mind. It could be a critique on something or something simple like telling what happened that day. I like to think of myself as a simple person but with a complicated head. I have ideas and thoughts that I want to get out but don't know to do it. So lets start off with something simple:

Little over a year ago, I had this idea of a screenplay. The idea came to me when I had just finished a run through of Modern Warfare 2. The idea was about two guys who live together and one day Russians invaded the country and the two guys turned into ghosts. Not real ghosts but a two man strike team who took out the enemy invaders one by one. I know it sounds like MW2 meets Red Dawn but the picture I'm creating in my head is a bit cooler. I've even toyed with the idea of turning the idea into a web series to be featured on YouTube. My main problem, I don't know how to get the picture in my head onto paper.

I've been thinking about this idea a lot lately since I haven't been working due to an illness. Hopefully, I can finally do something about it. Maybe, actually start writing something down on paper. Get some character ideas, scenarios, etc.

This is my problem, I'm a simple person with a complicated head. I want to do a lot of things but I don't know how to go about doing them. Along with this screenplay, I want to become a DJ, make electronic music people want to hear over and over again, release an album, travel to England, find the girl of my dreams, and there are tons more. Maybe, I'm just thinking to much about the thought and not enough on the process, or maybe I'm not focused enough. Who knows, but what I do know is that I have a list of things I want to do before I die and I'm damn sure gonna finish it.
