Draw The Line?

There is a line infront of me, it is barley visible and very fuzzy. 

I rub my eyes in hopes of it getting more clear, but with no success. I try to touch it and maybe if I use my sleve I can make it clearer. The line isnt there to be touched though, it is there to either stay fuzzy or become clear. Only when it is clear you can cross with both feet. Whatever you leave behind that line is then forever gone, just memories of a passed time. 

The line infront of me is a timeline.

 It either brings you forward or make you stay behind. It sets the time between what you want to come and what you are ready to lose. If I cross while it is fuzzy I might never experience what is coming and what I lost is then forever gone..
