Prepare your elevator pitch
As awkward as it sounds, a very interesting summary and
accomplishments will make everything for your conference
experience. For many shy people an early rehearsed pith will
help them to assist with the conference and making that
conference memorable.
Preparation is crucial but not the rehearsal, in reality too much
of rehearsal may lose your self-confidence and make you sound
dull, just focus on one thing that to be confident while
delivering the presentation.
