Stell euch vor, ihr habt eine funktionierende Zeitmaschine. Wohin geht die Reise zuerst?

There is no butterfly effect or any paradox in the case, so you can do what you want.

Then I’d try to figure out what that means. For example, if I kill Hitler if he’s still a nobody, what about the Second World War? Does he just come through another guide?

Otherwise, I would find out how dinosaurs really looked. And perhaps go further back until the limit is reached, from where you can no longer live on Earth, because the atmosphere has not yet the right composition or the temperature is too high.

I would also possibly turn to some trustworthy organization available to staff and protective suits to better explore this area of time. However, I don’t know how to secure myself so that this organization doesn’t abuse the time machine or cheat me.
