It’s quite challenging to appreciate the impact of our actions on others. Mainly because it takes time to manifest, and we are often too focused on what is happening in the moment.
But on the other end, it is delusional to believe that our actions have no impact. We do not operate in a vacuum, and when we say something, behave in a certain way, choose one option over another, people around us will make a mental note and work on some type of reaction.
The more intentional you are about what you choose to do (and not to do), the more likely the influence on others will be the one you want to have. Unsurprisingly, it all start with awareness.
