It is not so difficult to agree that change needs to happen. It is much more complex to agree on what change adds up to and act on it.
So, if you are an agent of change, there are two things to keep in mind.
First, small wins are wins nonetheless. You do not have to achieve everything at once, and even small changes in the right direction are something to be proud of. Building blocks that can support larger wins in the future.
Second, not giving up is part of the package. You might be tempted – you WILL be tempted – to give up once things do not look exactly how you had planned. That is precisely when you have to take a deep breath, buckle down, and reinforce the message around the need for change.
