One simple tactic I use for not wasting time and being more productive is writing down my to-do list everyday. I stick to the plan when I see it right in front of me. I check the tasks off when they are done too, as it makes me feel accomplished.
Another thing I do is delegate tasks to others when I can. Asking for help is not a sign of weakness and I'm not a super hero. There are only 24 hours in a day! This is an efficient way for me to get extra hours in my day.
Time efficiency in my research for my books comes by ordering all books and ebooks from the library in advance from my phone. Then I'm going to the library only once when most of them come in. Listening to books in the car while driving to and from my kids' activities saves reading time. Repeating aloud the important phrases on my iPhone recorder allows me to take notes on the fly and remember more from the repetition.
I have a personal character flaw which has turned out to be my biggest time gain. I have to be everywhere very early, like at least an hour. So, if there's no traffic and I do have that hour at my leisure, I have that time to answer emails from my phone, take notes from the books that I carry in my car, meditate, listen to peaceful music, write in my journal, or call my family. I also call in to the pharmacy and have my medicines mailed to me as a bonus time saver when early for work or events.
The biggest time waster is cruising Facebook and TV shows I really don't care about. Folks can do something better with their brains! TV shows that are on just to be on, but they don't really grab me is a time waster. I have learned to walk away and do something more productive. If I'm watching a silly show with my teenaged kids that I really don't understand, I'll offer an alternate activity to have quality time with them. If the show has value for their sensibilities then I excuse myself from the room. YouTube channels really irritate me (waste time) when my kids are watching other kids live their lives rather than living their own! Some shows on YouTube really are devoted to simple things like "a day in the life of 12 year old Cassie." (Ugh!)
