business plans and timelines are GOOD
BUT
if you force yourself to meet deadlines, your overall life might not get better... coz deadlines = stress (most of the time
)
thereby; you gotta be a tough one to force yourself a deadline, work hard to meet it, then due to lack of time work around the clock for two weeks in order to really completely meet that deadline... while you could have just as well moved that deadline a little forward, nobody's actually waiting for your work to finish (most of the time)
in brief; gotta be a tough one to force yourself to ruïn your life for a period of time...
