The pick is what connects your body to the instrument, and there is nothing more important. The use of your pick affects your game, but also the sound of the songs you play. Hence its importance.
Inexpensive, chances are you will find one that suits you perfectly and that will make your game more fluid:
Soft to very flexible picks are not very precise. They are generally used for chord beats on the Folk guitar or to set the rhythm.
The so-called medium picks are versatile and are the perfect compromise between rhythm and precision. If you are new, opt for this type of pick with which you can play different styles.
Picks from 0.90 mm and up are very accurate. They are perfect for solos or improvisation.
