I need some help and advice re some of my stocks

My gut feeling, DOCU is kind of baked in, almost a utility. Where’s the phenomenal growth? I own them but I’m thinking of trading for TTD, though I’m wary of advertising, or adding to ZS, OKTA. (Who doesn’t want better security?) I fear TTD may have a shorter run once they get the low hanging fruit.

But I really know nothing…
