Finally landed my first job after taking my classes 3 months ago

I was getting ready to give up soon and just go back to my regular life of working at the daycare but I finally landed a job at the blood bank🥳I’m just here to encourage people to keep going I know it’s hard trying to find a job because everyone wants you to have experience blah blah. But I’m telling you it’s going to be someone who doesn’t care you have no experience and open that door for you. I will only be making 18.50 but this is alright for me considering me being 19 I just am glad to have a spot finally and use this job as a stepping stone to one day work at a hospital hope all is well and everyone finds a job. Any advice for when I start working? I start next month
