Small actions every day.
To know what actions to take you need to know where you're going (= having a vision) and what you're committed to doing every day to get there (= your mission.)
Knowing how you want to be seen by others will help you choose the right actions (= your core values).
Defining WHY you actually want to build this brand and be successful with get you through the days when thing don't seem to fall into place. It also help you find people who believe in the same things and have a similar vision and values. (= your brand purpose)
If you don't know where to start building your brand, start with your Brand Essence (purpose, vision, mission, core values) - aka the hearts and soul of your brand.
Share you purpose in the comments if you dare.
