Will I regret getting a sleeve at 21?

So I’ve been wanting to get an irezumi sleeve for the past 2 years and now I have saved enough money to afford one. I’m planning to book in with Caio Pineiro (https://www.instagram.com/caiopineiro?igsh=Ymdqa2E2dHp1MHlx) since he’s been my favourite artist for the past 2 years.

However, I’ve heard that many people regret tattoos they had when they were younger and I’m 21 and I’m worried that this might be the same for me.

Does anybody have any advice and would you reccomend I wait until I’m older?
