In all honesty, it’s the same in private life and in sports too (amateur and professional leagues alike). After all, basic human behavior doesn’t really change whether the person changes their outward appearance with a suit or a blue collar uniform. Humans are set up to primarily maintain the best current status quo or their “comfort zone” (see also blog no. 22).
So the worst acceptable mistake would be for people to welcome change. As my greatest reward is the maintenance of the status quo, I hold onto the current (so the “old” in this moment) with all my might. Sometimes, companies and organizations talk about somebody being stuck in their ways. And that’s just one expression for it.
When I hold onto the old, I can’t discover new lands. So the logical conclusion could be that you should first tackle what you’re leaving behind and letting go before setting out for new territory. If I stick to my old ways, I can’t welcome new ways. Even they’re right in front of me. When I used this image a few years ago when talking with the decision-makers in an unsuccessfully completed project (it was about a CRM integration attempt that was still not successful several months after the integration), one of the decision-makers said, “…well, let’s make people let go. We’ll take away their old ways (Excel) and they’ll just have to use the new ones (CRM).”

So, our advice is to first ask yourself the following questions before you want to start something new:
