I think any 'enjoyable' profession - there is always lots of competition.
There are literally hundreds of make-up artists, photographers, models, nail techs, hairdressers beauty therapists, chefs, cake makers, artists, fashion designers, interior designers. Anything that has creativity surrounding it, that can identify one from another.
Thats not a bad thing tho.
All winners never give up - so if you want to stay in your profession you have to fight for it and if you want it badly - you will succeed.
And, never listen to other people opinions - if we all did that, we would never do anything in life.
