Kicking myself...Closed HPQ way too early

Here is how much I missed the HPQ rally by. Really kicking myself for not having more faith in my employer...lol

Whatever. Now the rally really is over, thinking of going short for the correction that looks very likely based on this chart.

Which is worse for your trading mind? Getting out too early and seeing that you could have made more profit? Or getting out too late and seeing profits you already had never realized.
