We start by getting organised and prepared. All jobs are made so much easier with good preparation.
Knowing who you are talking to and what you are going to say is so important. Check out day 8, 9 and 10 in this video.
Know your choices, Know what is achievable, know your why, know what you already have.
Start with the Must Have Not Negotiable Stuff. 80 % of what is effective can be done with 20% of the work so work out what will get you the best return on your time.
