+ Strength > - 4 of wands > - The Fool
Strength sums up your current intent on this startup. You feel that you have the mental capacity and fortitude to strive through this, especially if you intend to juggle an employment with the business. Qualities-wise, seems like you do have the courage, instinct and confidence to do so.
However, your actions (or at least actions intended) may ruffle quite a few feathers. In your eagerness and ambition, you would have failed miserably in communicating with associates, friends and family, causing misunderstandings and problems that would ruin your chances of success. There will be issues working in a team (both new venture and employment work); lack of focus such that you may neglect family or push work to others, etc.
Lastly your outcome doesn't seem to end well. The eagerness to succeed is likely to be your downfall, as you charge forward and ignore all consequences of your business decisions. There will be plenty of opportunities for others to take advantage of you, hence, need to bear in mind of what you may potentially do here.
General answer, not recommended to start this until:
1. You can fully focus on venture without the need for side employment simultaneously
2. You have fully discussed with your family on your plans and garnered their support
3. You take it slow and make decisions for reasonable growth at achievable timelines.
I can't tell what industry though... It seems open ended or maybe not skillful enough yet to do so
