I have €7K to invest and 6 months

Ive tried drop shipping in the past but failed a few times. I have a well paying job now and I’m about to go for a 6 months unpaid leave, I have about 7/8K in € to invest in a drop shipping/ e-commerce business, my goal is that after the 6 months I can pay myself a salary from the business and don’t have to go back to my job.

Like is said I tried a few times drop shipping but failed, I found a mentorship called Scaling With Ecom it cost €3400,- with daily calls and training I am really considering to join the mentorship and use the rest of the money for testing products and creating creatives etc.

Or I use the full 7/8K for testing etc.

What would you do?

Anybody heard form Scaling With Ecom?

Thanks for your honest feedback.
