Time is precious. If you treat it right, it can be your friend. If you neglect it, it will bite you 11 times out of 10.
Some people out there may be reacting by thinking they can just bring in additional resources and double the effort in the same amount of time. Realistically, you haven’t actually bought new time, you are now using the time of two (or more) people. You are expending time at a faster rate than before.
Taking time to plan is the best way to not waste this resource. Sometimes it will be best to wait until right before the deadline to start. Other times you have to start and finish well before the deadline. Circumstances and experience will dictate the approach you should take.
Working through a weekend to catch up on things doesn’t solve your time problem as you are robbing time from your own downtime for work. Much like sleep, it’s hard to catch up on lost time. You’ll struggle to get where you want to be. Maybe you’ll catch up or maybe you’ll just let it go and start on the next thing.
That lost time will weigh on you. Inefficiencies always do.
