What are the problems I can face, be honest!
I want to start an Instagram and TikTok page about fitness and physique. I look very good and I would post content about physique + educational content about fitness (exercises, work outs, tips and tricks....). Then after I gain some followers I will drop my merch. Whole time from the first video I will push one sentence, one ideology (something simmilar to nikes "just do it"), I believe that that is really important for branding and recognition. My merch will be heavily based on that sentence.
This is my firts time doing it and I don't know which problems I could face, be honest. Any area, any problem, any aspect, I need to be prepared.
