If you are just starting out, it helps to be on the lookout for the natural impulse to talk with other people about your meditation practice or to casually mention that you are beginning to meditate.
It is easy to dissipate your energy in this way. If someone doesn’t respond positively to what you are sharing with them or slights the idea of meditation in any way, even unintentionally, you may become discouraged before you even get started or build enough constancy into your practice so that other people’s opinions don’t matter to you in this regard.
Also, if you wax enthusiastic about your meditation practice and how great it is, and this becomes a habit, pretty soon you may be wasting what little energy you have talking about your meditation “experience” and how great your “insights” are, and how wonderful and transformative mindfulness is, rather than practicing. The risk is that pretty soon you won’t have any time to meditate any more; you will have become more involved with the story of your meditation practice than with the ongoing experience of meditating. This, of course, is more selfing manifesting itself, only now it is being built around the subject of mindfulness. It is endlessly amazing what the mind will do to construct and reinforce an identity.
For this and other reasons, it would be useful to bring some care and attention and intentionality to whom you feel impelled to speak with about your meditation practice and to what you wind up saying. It can be very helpful to have at least one person — hopefully someone who is also practicing and who is more experienced than you are, or who at least has been at it longer — with whom you can talk about your practice in some detail. But other than that, it is probably best to minimize how much you talk about it with others beyond just explaining what you need to to family and friends who might be interested. That way, you won’t waste the nascent energies you are mobilizing that are necessary to keep up the momentum of formal practice through thick and thin. In a sense, you are reinvesting those energies, pouring them back into the practice itself and into your growing relationship with silence and non-doing.
You are letting how you live, your actions and attitudes, speak for you with no need to synthesize a satisfying narrative for others, or even for yourself.
