Get three things done per day and make sure you do them well. No need to plan for more as long as you achieve these three substantial things that are a priority to you.
And of course 2 minute tasks are priority at any time during the day. That's why Business Ideas takes no more than 2 minutes to get started!
Remember if you think your days are too short: don't do anything and you'll have 24 hours of spare time every day! ;)
