Dealing with stress

I finally landed an apprenticeship. This is really good because i got to convince the guy i really wanted to teach me how to tattoo. I'm really passioned about it and aim to be able to do nice work someday so i didnt' wanna have to be self thought and have to break bad habits after... My mentor yet is gold, he puts me in difficult situations sometimes but always come back right on time before i make a mistake that couldnt be corrected. I am very stressed when he watches me sometimes tho... I think there are two main reasons: 1) The guy is a fucking legend in this town, he's been tattooing for like 30 yrs now... I know i'm very lucky to have him teach me as any of the guys who i talked to before told me "The old man wont teach anyone..." I know he's watching my evolution closely (He told me he'll know before two months if i'll eventually pick it up good or not...) 2)He's got this very army like approach sometimes lol Wich kinda help me remember ll the shit i have to remember but kinda stressful to "Where's your vaseline?/Didnt i tell you to dip more?/Youre not supposed to filled this way are you f***n deaf!/I told you 2 times P,it's not like ima do it for you, i aint yer mom!" lol Yeah, he seems to realize it tho... I did good on tattooing my friend Friday so the boss decided that yesterday was my first tattooing day... We do not do much custom work, it's more a street shop so my first day had to be that busy saturday where everybody was busily busy (to the point where i had to trace out some shit for the guys just so they can keep up with the pace). So yeah, i had to be on my own for the 1st time and this got me freaking nervous again... I got to finish the two tattoos i did but i felt like i was at max. 60% of my own capacities. That all has to do with stress. Anybody got a similar experience and found a way to reduce the stress level... I know it sure may come with time but i'd like to hear peoples way to reduce their own.

Well, I personally have this kinda over optimistic outlook on the stuff that I do. Some might think its some kinda asholeism but im just confident and look at people as what they are. PEOPLE. They are just human beings. My friend said to me that he has a hard time asking a local artist to do a interview with him, when I dont really think twice of emailing to someone like Grime. Just because I think of them as human beings, just like I am, and not some golden gods. That doesnt mean that you wouldnt have to respect them. I do as I do all the people. Do to other's like you would like to be done to you. And your boss is propably giving you a hard time because sometimes customers also can be like that. Because being a tattoo artist isnt just about being able to tattoo. Its about interacting with people, good and bad. So his actually doing you a favor. His training you because obviously he likes you and believes in you.Othervise he wouldnt have taken you as a apprentice. Hope this helps :)
