This is one of those lessons that I've heard a lot of feedback on and so many have said that it really helped them make the changes they wanted to make. I have likened working against things to rowing a boat upstream or swimming upstream. We are working, stressed out because we are pushing against a current of affairs. Sometimes it seems like the harder we work, worry, or fight, the slower our progress. Part of the reason is that our own energy is helping the river to flow, and we then are struggling against it.
So, going with the flow, then, is simply to relax. Stop the struggle. Go with the flow. Put the oars in the boat. Trust the outcome and watch what happens. It's magic.
Sometimes if I am talking with someone and it just feels like a struggle, I remind myself of this and just shut up and listen, pay attention to them without judgment, and let it flow as it will. Every time it works better. It amazes me how much of a relationship you can create by just listening as much as possible and encouraging them to talk more. Plus, it keeps my foot out of my mouth more often too.
