A part of everyone knows when they are being true to themselves. It is a case of tuning in and listening to oneself. Meditation is a good way to do this. So is just going with your feelings. You can sense (on some level) when you aren’t behaving in a way which enables you to do this. The ‘clue’ is to tune in and change your focus or behavior the moment you sense this happening. One small step at a time allows things to go more smoothly and allows you to change things which impede this.
