How to choose a sideline?

First of all, you need to weigh the pros and cons of your main business and sideline business. The main business is usually a stable source of income, and may also provide benefits such as welfare and pension plans. At the same time, the main business may require more time and energy, as well as higher work pressure. The sideline may not be as stable as the main business, but it may be more flexible, more adaptable to your time and interests, and make you more creative and independent.

Secondly, you need to evaluate whether your success in sideline business is sustainable. If your sideline is based on some popular trends, it may only be temporary. If your sideline depends on certain skills or resources, then you need to consider the sustainability and substitutability of these resources.

Finally, you need to consider your personal goals and values. If your main goal is to obtain stable income and welfare, then your main business may be more suitable for you. If you pay more attention to autonomy, flexibility and creativity, then sideline may be more suitable.

In a word, this is a complicated decision, which requires you to consider many factors comprehensively. I suggest you take the time to think and consult professionals to help you make the decision that suits you best.
