You can only have 1 top priority - are you focused on it right now? focu.sh can help.
Focu.sh is a just a little script. Copy-paste, curl, or wget yourself a copy.
It doesn't really matter - /usr/local/bin, $HOME/bin, or whatever you like.
Create a file ~/.focush and keep it up to date with a description of what you should be focusing on.
./focu.sh or ./focu.sh & etc.
Just edit ~/.focush and get back to work :D
