Take great care to be consistent with what you say and what you do. Your actions must match your speech.
For this reason, it may be advisable to stay quiet so as not to trap yourself in the net of your own words and commitments. You run the risk of being contradictory in the future by proclaiming something too bold in the present.
As much as you can, prove your beliefs through demonstration rather than explanation. This is difficult for someone who writes, but the remedy is simple—tell with story what you might with an explanation.
