Rapid Play Advice

Hi there. I hope you are well. I have been away from chess busy trying to perfect my PhD on Phenomenology (don't ask). I have been asked by a friend to take part in our local Rapid Play competition, on Sunday 6th April each game 30 minutes, 45 moves with that 30 minutes. I have played Rapid play only once before, and whilst I will be playing people with the same ECF scores as me i.e novices, I have never been comfortable with Rapid play, I guess because I don't see Chess as a game of speed, part of me has sympathies with Fischer's idea of a Timeless game, although my one favourite players Mikhail Tal was a great Rapid and Blitz payer. Have you any advice for me?
