Eliminate your counterproductive speaking tendencies before adding new skills
There is a saying that goes “the good is often a result of the absence of the bad.” In other words, focus on subtraction before addition.
When it comes to public speaking improvement, identify the speaking tendencies that are negatively affecting your credibility and impact, then focus on eliminating them.
Do you find yourself anxious before you speak because you did not prepare enough? Then add more preparation time next time.
Do you use a lot of credibility-bruising verbal fillers like um, yeah, and like? Then focus on pausing more and incorporating silence.
Doing this will enable you to see more immediate and impactful results from your time invested.
