In a trader's perspective: assuming you're a decent trader, then just set your plans and price targets, and totally stick to your plan. If your emotions still get a hold of you, then you either toughen up or just admit that trading is not for you.

In an investor's perspective: Though I like buying at dips, I mostly don't even look at charts and time entries lol. After approximately 4 years of holding, FUD and negative posts in general pretty much does nothing to me. Knowledge and experience will simply make you realize that all of those are just small bumps and hindrances for the long term.
