I have a trello board with the following columns:
"Good intentions" :- Things I think I'm going to do. I investigate then put in other columns.
"Next Up" :- Need to have a go at next.
"Working On" :- Actively doing.
"Done/Dead" :- Things that I did as well as things I failed at or discarded.
"Follow Up" :- Something happened, so need to wait on something/someone to then allow me to continue.
"Asleep" :- Sometimes things are not 'Dead' they are just really not worth looking at for another year or so. I evaluate these projects once a year or and move them into Next Up if viable again.
It's my home page when I fire up my browser. ;)
