“I’m not an expert, but….”

Phrases like — “I’m not an expert, but…” and his popular cousin — “I’m not sure if this is a good idea….” are harmless prefaces for relaxed brainstorming sessions. But if you’re in a situation where you’re trying to get people to respect you and take your ideas seriously, these phrases undermine your credibility.

Consider taking a more direct and less self-deprecating approach instead — “What I believe is the best direction is X” or “I would suggest we also consider Y.”
