If you want to change something about yourself it is best to start with a conversation.
This will probably be a conversation with yourself in the first instance, and then later a conversation with someone you trust.
It’s OK to keep things to yourself, for a time. In fact this is good advice until you have thought things through a bit, but don’t leave it too long if you are serious about the change you want to have happen. The reason it is useful to discuss ideas with another person is that conversation unlocks the mind and generates ideas in a way that we just can’t do alone.
It is not necessary to know how you’ll go about making change happen, only that you intend to have it happen. Conversation will sow seeds and ideas will germinate.
And now’s a good time, it is Spring, after all.
