Let's get straight into it.
1. Stay in your own lane and have your own vibe. What I mean by this is basically having tunnel vision for your brand and aesthetic. Don't go chopping and changing your style, branding, website and products just because you see Tom, Dick and Harry doing it. Yes you can take inspiration from other people and brands but remember to have your own ideas and trust yourself when building your brand.
2. Be prepared to spend money. Starting a brand ain't cheap, not to say that it can't be done on a budget but it just may take longer than expected without some initial push from your own pocket. It's not always sunshine and rainbows so be prepared for the ups and downs as it is an emotional rollercoaster and nothing comes easy.
3. Test Test Test. You have to try and try and try different ideas, concepts, get different samples made, speak to customers and get feedback. You most likely won't strike gold with the first idea that comes to your head. If you feel like you've finally found the right product or products then go to town with it, believe in it with all your being and get it out into the world.
Don't be afraid to fail and keep moving forward, remember it's about the journey and the process not the end result.
