You should start to establish your personal brand as a startup company as early as possible. Here are the main three reasons:

1. Value Growth Over Time: Starting your personal brand early allows for a higher growth rate. People can witness its evolution, making your brand more engaging and rewarding. A well-established brand with high value grows more slowly, reducing its perceived growth potential.

2. Preparation for Stock Exchange Listing: Early growth and development are crucial for a potential stock exchange listing. The sooner you start, the more time you have to build your brand’s value and prepare for this significant step.

3. Community Engagement: An early start lets your community be part of your brand’s growth journey. Their contributions shape your brand from the beginning, enhancing loyalty and engagement. This sense of impact is particularly motivating for your community.

In essence, starting early increases your brand's value, prepares it for a stock exchange listing, and strengthens community involvement.
