No, lovely soul, you don't.
There will be options to bulk download 5 days (+ bonuses) at a time or download each day at a time.
Whilst there is the chance that I will delete the content once I feel the series is no longer applicable, I shall contact everyone who has purchased it before doing so, so you have time to download everything.
I do recommend that, at the very least, you download each day (plus any bonuses) as that day comes around. This video series is designed to last 25 days and I recommend you do set aside time every day to watch the video and review any accompanying bonus.
I find if you take a day off, it's always so much more difficult to restart.
