If you're not a professional, if you're not yet a professional then this is the time to pretend like you are. The word professional is overrated, a lot of people think of it as something attached with greatness, perfection and super high level work.
The word professional just simply means you can do the job on time. It simply means being prompt and giving the client relief from worries. You simply give the client a piece of mind that you can deliver without any form of delay.
Pretend that you can do something and you will be able to do it. Pretend that you know a lot, pretend that you've been doing your work for a very long time without panicking or making mistakes.
Fake it till you make it, but make sure you will still give your very best and 100 percent effort. Forget about the pressure, it is nothing, just remember that you still need to move regardless if you are feeling good or not. Just think about what you need to do and that's it. Forget about the situation, forget about the difficulty, forget about the people around you. Stand straight, pretend that you're confident and just do your job.
The more you do things consistently, the more you show up and never fail your clients... the faster you will become a professional. And maybe you're already a professional, you just need to become a little more confident.
Everyone starts being an amateur so there is nothing wrong with that. Some amateurs even act like they were already a professional so they look like one.
It is how you feel towards yourself, if you feel like an amateur then you will produce an amateur results but if you feel like a professional and act like a professional then you will produce awesome and unbelievable results.
