Hey Dizzy321,
I would like to thank you for that
YouTube comment, I'm glad that you're a part of the site.

As far as tough keys go, it's like anything else, you just got to get used to them.
I talked to retired navy trumpet player, a really good player by the way. He could bust out all these great jazz licks over tunes in Bb, G, F, C, etc.. But couldn't do anywhere near the same in F#, E, C#, B, etc...
What he did was use
Band in a Box. He took real book tunes and changed the keys to the more difficult ones. After awhile of doing this he really started sounding more fluent in the less played keys. This made it even easier for him to bust out great licks in the easier keys.
I think learning licks in 12 keys is a really good way to become fluent on the trumpet in every key. The more you play in all the keys, the easier each one gets. That's why I'm such a huge advocate of learning licks in 12 keys. Not only does it give you more ideas, it also builds your overall technique on the trumpet.
