You have a good BaZi , one that is good to start and manage your own business. However, the time is not right. You are currently going through an "ungrateful punishment" phase, which ends by the time you reach 33 years of age. During this period, you are often trouble by conflicting thoughts and cannot see the trees for the forest. You need to focus. But this is something you are weak at doing right now. 

The best type of industry for you belongs to Wood. Since you are Yi Wood, and wood helps pacify the fire-water clash in your chart, this industry offers the best opportunities for you to excel. However, you will only discover the opportunities in the next luck pillar. At the moment, your mind is divided between relationship and career. 

The current relationship will take it's toll if you don't find time to nurture and provide value. I would say for now, focus on building a stronger relationship while preparing for your venture in the Wood related industry. 

Learn how to grow (wood) a business, not just start one. This means - you need to master marketing, innovation and promotion skills/knowledge. 

Good luck. 

Warm Regards,

JY
