I suffer a lot from this but from a rather curious perspective. I have so many things to do,pen turnering, portraits (commissions),woodworking projects to start,home maintenance,dog walks and training (puppy) unhealthily chess obsession (online) that l get overwhelmed and don’t know what to do so usually l play chess and deal with the pup. Next thing you know the day is over with what seems like nothing done. I need more determination to just focus on one thing at a time.
