How to avoid frustation in a session?

I bought the helix trident 2 months ago and used it 1-2 times a week. The first sessions were great and i enjoyed the new experience but now im getting frustatated mid a session. After 30 min in im getting frustated that and bored. Also i have the problem that i have to much expectations which lead again to frustation. How can i get the proper mindset for a session? How do you guys do it?
